Answer:

[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]

Step-by-step explanation:

Given that:

Length of a rectangle = [tex]3x^2-4x+5[/tex]

Width of rectangle = [tex]2x + 1[/tex]

To find:

Simple polynomial expression for finding the area of rectangle.

Solution:

First of all, we should know about the formula for finding the area of rectangle. Then we should know how to multiply two polynomials.

Formula for area of a rectangle in terms of its length and width is:

[tex]Area= Length \times Width[/tex]

Putting the given values:

[tex]Area = (3x^2-4x+5)(2x+1)[/tex]

Here, we can use the distributive property of multiplication for finding the value of the above multiplication expression.

[tex](A+B)\times (C+D) = A\times C + A\times D+ B\times C + B \times D[/tex]

Therefore, the multiplication of above polynomials can be written as:

[tex]Area = (3x^2-4x+5)(2x+1)\\\Rightarrow Area = 3x^2(2x+1)-4x(2x+1)+5(2x+1)\\\Rightarrow Area = 6x^3+3x^{2} -8x^{2} -4x+10x+5\\\Rightarrow Area = 6x^3+-5x^{2} +6x+5[/tex]

Therefore, the answer is:

[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]

Answer:

8x² + 8

Step-by-step explanation:

Given

(x² + 3)² - (x² - 1)² ← expand both factors using FOIL

= [tex]x^{4}[/tex] + 6x² + 9 - ([tex]x^{4}[/tex] - 2x² + 1) ← distribute by - 1

= [tex]x^{4}[/tex] + 6x² + 9 - [tex]x^{4}[/tex] + 2x² - 1 ← collect like terms

= 8x² + 8

Answer:

-8(x^2 - 1)

Step-by-step explanation:

(x^2 + 3)^2  and  (x^2 - 1)^2 are both squares of binomials.  The first step here is to expand both:

-(x^2 + 3)^2  =  -x^4 - 6x^2 - 9

(x^2 - 1)^2     =  x^4 - 2x^2 + 1

Combine the two right-hand expressions, obtaining:

-8x^2 - 8 or -8(x^2 - 1)

This -8(x^2 - 1) is the simplest form of the given expression.

If desired, -8(x^2 - 1)  can be factored:   -8(x - 1)(x + 1)

Answer:

  3.4 < x < 7.2

Step-by-step explanation:

The length of the third side of a triangle is always between the sum and difference of the lengths of the other two sides.

Here, the difference is 5.3 -1.9 = 3.4; the sum is 5.3 +1.9 = 7.2. So the length of the third side must satisfy ...

  3.4 < x < 7.2

_____

Additional comment

The difference in side lengths is what you get when the shorter side is folded over the longer one. The excess of the longer over the shorter is the difference. If the triangle is to have non-zero area, the third side must be longer than that.

The sum of side lengths is what you bet when the two given sides are laid end-to-end. If the triangle is to have non-zero area, the third side must be shorter than that.

These statements are variations on the "triangle inequality", which states that the sum of any two sides must exceed the third. (That will always be the case if the sum of the shortest two sides exceeds the longest.)

Step-by-step explanation:

Answer:

or, x2-2x-15x + 30= 0

or,x(x-2)-15(x-2)=0

Step-by-step explanation:

12x-3=17+7x

12x-7x=17+3

5x=20

x=4

Answer:

4

Step-by-step explanation:

Given that:

12x - 3 = 17 + 7x

Collect like terms

12x - 7x = 17 + 3

5x = 20

Divide both sides by 5

5x / 5 = 20 / 5

x = 4

Hence, x = 4

Answer:

25 weeks

Step-by-step explanation:

step 1. find y which is what you are trying to find which is how long it will take for drake to make $1200

step 2.- subtract 450 from each side

1200=30x+450

-450           -450

750=30x

step 3.- divide by 30 on both sides

750=30x

30    30

x=25

i dont know if this helps but i am still learning how to explain on here. :)

Answer:

it will take him 25 weeks

Step-by-step explanation:

because 1,200 - 450= 750, and 750 divided by 30 is 25, therefore it will take him 25 weeks.

Answer: 3 students

Step-by-step explanation:

You can solve this using the expression;

Total = A + B + C - Both - all - neither

Where A, B and C represent those taking one class

As each student must take at least 1 class, there is no 'neither'.

37 = 12 + 18 + 19 - 9 - All

37 = 40 - All

All = 40 - 37

All = 3

Answer:

3

Step-by-step explanation:

I added the number of students enrolled in each class. It equaled 49.

I subtracted the number of students from that amount

49-37= 12

I subtracted the number of students enrolled in two or more classes

12-9= 3

3 are enrolled in 3 classes

Answer: 1.953125e+15

Step-by-step explanation:

Answer: Than did not use 0.06 for 6 percent.

Step-by-step explanation:

From the question, we are informed that Than computed 6 percent of 38 as 6 percent of 38 = 0.6 times 38 = 22.8.

His above solution is wrong. We should note that:

6% × 38

= 6/100 × 38.

= 0.06 × 38

= 2.28

The mistake that he made was that Than did not use 0.06 for 6 percent.

Answer:

65% of 40 is 26

26 is answer

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$40=100\%$.

Step 4: Similarly, $x=65\%$.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$.

$x=65\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{65\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{65}{100}$

$\Rightarrow x=26$

Therefore, $65\%$ of $40$ is $26$

Answer:

x=-16

Step-by-step explanation:

−2(x+14)+1=5

Step 1: Simplify both sides of the equation.

−2(x+14)+1=5

(−2)(x)+(−2)(14)+1=5(Distribute)

−2x+−28+1=5

(−2x)+(−28+1)=5(Combine Like Terms)

−2x+−27=5

−2x−27=5

Step 2: Add 27 to both sides.

−2x−27+27=5+27

−2x=32

Step 3: Divide both sides by -2.

−2x

−2

x=−16

Answer:

x=−16

Answer:

-2(x + 14) + 1 = 5

-2x - 27 = 5

-2x = 32

x = -16

d(5) = 5

Step-by-step explanation:

The nth term is given by :

[tex]d(n)=\dfrac{5}{16}\times 2^{n-1}[/tex] ...(1)

We need to find the 5th term of the above sequence. For this, put n = 5 in the above formula.

[tex]d(5)=\dfrac{5}{16}\times 2^{5-1}\\\\=\dfrac{5}{16}\times 2^4\\\\=\dfrac{5}{16}\times 16\\\\=5[/tex]

So, the 5th term in the above sequence is 5.

Step-by-step explanation:

all of them could be made into a difference of squares since they all have a minus sign in the expression, but maybe the question is if they can easily be made into a difference of squares.

[tex]p^{8}[/tex] - [tex]q^{4}[/tex] => [tex](p^{\sqrt{8} } )^2[/tex]-[tex](q^{2})^2[/tex]  could be but not easy

Answer:

5 times

Step-by-step explanation:

What we need to do here is to find the lowest common multiple of 7,8,11 and 12

This is;

1848

Now, let’s calculate the number of seconds in 3 hours

In 1 hour, we have 3600 seconds

In 3 hours, this will be;

3600 * 3 = 10,800 seconds

So, to find the number of times in which all 4 will toll together, we need to know the number of 1848 seconds in 10,800 seconds

Mathematically, that will be;

10,800/1848 = 5.844

Our answer will be 5 times however

This is because the sixth time they would have sounded together would be more than the 3 hours time frame

Answer:

Equation: x(n)=2*4^(n-1)

a6=2048

Step-by-step explanation:

Take note that the common ratio is 4 because 2*4=8, 8*4=32, 32*4=128, and so on...

We will use the equation x(n) = ar^(n-1) where n represents the nth term, r stands for the common ratio, and "a" stands for the first term. We use (n-1) because ar^0 is for the 1st term

Given the first term is a=2, the common ratio is r=4, then we have the equation x(n)=2*4^(n-1)

So, 128*4=512 would be the 5th term, and the 6th term would be 512*4=2048

So a6=2048

We want to find an equation and the sixth term of the given geometric sequence.

The equation is:

[tex]A_n = 4*A_{n-1}[/tex]

And the sixth term is equal to 512

In a geometric sequence, each term is a constant times the previous term, so the general relation is:

[tex]A_n = k*A_{n-1}[/tex]

Here we can use any pair of consecutive terms to find the value of the constant, for example, if we use the first two, we have:

8 = k*2

8/2 = 4 = k

Now we know the value of the constant, then the general formula is:

[tex]A_n = 4*A_{n-1}[/tex]

Now we can use this to get the sixth term:

[tex]A_6 = 4*A_5 = 4*128 = 512[/tex]

Step-by-step explanation:

If the ratio of raisins to M&Ms in a bag of trail mix was 2:3, that means that there are 2 raisins for every 3 M&Ms. This means that in a bag of 100 items, there would be 40 raisins and 60 M&Ms. I'm not sure what the ratio would be as a fraction (maybe 2/3?), but I do know that the fraction for the number of raisins in the whole bag is 2/5 and the fraction for the number of M&Ms is 3/5.

Hope this helps!
