n²+13n+40,

This is why;

Observe only the right side. The number is (n+8)(n+5).

Let's elaborate on that using FOIL.

F = When we multiply the first two terms, n and n, we obtain n².

O = outer instructs us to multiply n by 5 to get n*5 or 5n from the outer terms.

I = inner instructs us to multiply the inner expressions 8 by 8 and n by n to obtain 8n.

Since 8 and 5 are multiplied by L, we obtain 8*5 = 40.

Add up the outcomes: n²+5n+8n+40 = n²+13n+40

Observe how the phrase is a little bit simplified by the combination of the like terms (5n and 8n).

This demonstrates how (n+8)(n+5) becomes n²+13n+40, becoming the correct response. For all values of n, none of the other options are valid equations;

The number of movies that will give same cost is 14 movies.

From the information, the cable company charges its customers $4 to rent a movie and an online membership costs $21 and members pay only $2.50 to rent a movie.

Let the number of movies for same cost be represented by x. This will be:

(4 × x) = 21 + (2.50x)

4x = 21 + 2.50x

Collect like terms

4x - 2.50x = 21

1.50x = 21

Divide

x = 21/1.5

x = 14

The number of movies will be 14

When he walked a constant 4 miles per hour on the level road, 3 mph on uphill and 6 mph on downhill, then he walked 20 miles

Given,

A man walked for five hours

First he walked along a level road, then up a hill, then he returned around and walked back to his starting place along the same route.

We know,

Speed = Distance/ Time

Time = Distance / Speed

The speed when he walked on the level road = 4 miles per hour

Distance traveled on the level road = A

Time taken = [tex]\frac{A}{4}[/tex]

The speed when he walked on uphill = 3 miles per hour

Distance traveled on the level road = B

Time taken = [tex]\frac{B}{3}[/tex]

The speed when he walked on downhill = 6 miles per hour

Time taken = [tex]\frac{B}{6}[/tex]

Then he walked level road again

Total time taken = Time taken on level road+ Time taken on uphill+ Time taken on downhill+ Time taken on level road

[tex]\frac{A}{4}+\frac{B}{3}+\frac{B}{6}+\frac{A}{4}=5\\ \frac{3A+4B+2B+3A}{12}=5\\[/tex]

The value of l is. We use simple substitution of values to find the value of l is 48.

We have been given the equation V=lwh where l is the length, we can say that the given equation is that of volume of a cuboid where l is the length, w is the width and h is the height of the cuboid. We know the values of V,w and h. We have to substitute the values of V,w and h in the equation V=lwh inorder to find the value of l. Substitution method is generally used for solving system of equations where we first solve the value of one variable and then substitute the value in the other equation to find the value of the other variable. Since we only have one equation and we know the value of 3 of the 4 variables we only have to solve for one.

V=lwh

l=V/wh =[tex]\frac{576}{6.12} =\frac{576}{72}[/tex]= 48

The dimensions of the rectangle =  6 ft

Along with arithmetic, geometry is among the oldest subfields of mathematics. It is concerned with spatial characteristics like the separation between objects, their shape and size, and their relative positions. Geometer is the term used to describe a mathematician who specializes in geometry.

At a fundamental level, geometry is essential to understand because it lays the groundwork for learning more complex mathematical concepts. Raj Valli, the founder of Thinkster Math, notes that algebra and geometry frequently overlap. In science and math classes, it introduces crucial formulas like the Pythagorean theorem.

length = 2w - 1

We know that the area:

Area = length * width

Area = 2w - 1 * width

A= 2w^2 -w = 21

2w^2 - w -21 = 0.  Solve for w using quadratic formula.  

[-b±√(b2 - 4ac)]/2a

[1± √((-1)^2 - 4*2*(-21))]/(2*2)

[1± √(1+168)]/4

w = 3.5 ft

length = 2w - 1

The number of uniforms the Spartan Basketball team purchased was 13.

The number of uniforms bought by the Spartan Basketball team can be determined using the mathematical operations of subtraction and division.

In the first place, the cost of equipment is subtracted from the total cost.  The remainder is divided by the unit cost of uniforms.  The quotient is the number of uniforms bought.

Total cost incurred = $1,860

Cost of equipment = $300

Remainder cost = $1,560 ($1,860 - $300)

Unit cost per uniform = $120

The number of uniforms bought = 13 ($1,560/$120)

It is given to us that the conditions for the tree digit area code are:

first digit could be any number from 4 through​ 8,

the second digit was either 4 5 6 or 7, and the third digit could be any number except 2 or 7

Using the conditions above, the digits which can be first digit of code = 4 through 8 =4,5,6,7,8

the digits which can be second digit of code= 4,5,6,7

the digits which can be third digit of code = 0,1,3,4,5,6,8,9

number of possibilities for first digit= 5

number of possibilities for second digit=4

number of possibilities for third digit= 8

Therefore, total number of possibilities of code   = number of possibilities of first digit x number of possibilities of second digit x number of possibilities of third digit = 5 x 4 x 8=160

Answer: $1,372

Step-by-step explanation:

If using the Labor Statistics Document

A men’s median weekly earning with Bachelor’s degree only is $1,384 * 4 weeks = $5,536

A women’s medium weekly earning with a Bachelor’s degree only is $1,041 * 4 weeks = $4,164

Subtract $5,536 - $4,164 = $1,372

The full sentences are:

The typical monthly salary for women with bachelor's degrees is $3,020.

The typical annual salary for a guy with an associate's degree is $36,432.

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

Every month has four weeks.

The median monthly income is thus:

Earnings = 4 * $755

Earnings = $3020

As a result, the typical monthly salary for women with bachelor's degrees is $3,020.

The median annual income:

A man with an associate's degree makes $759 each week.

A month has four weeks, while a year has twelve months.

Hence, the annual median income is:

Earnings = 4 x 12 x $759

Earnings = $36,432

Thus, the typical annual salary for a guy with an associate's degree is $36,432.

The simplified value of the maximum weight is 9.62 and the minimum weight is 9.18. Also the function for the maximum and minimum weight is y + x and y - x

Here,

Given that, A package with a labeled weight of 9.4 pounds can have an actual weight plus or minus 0.22 pounds.
Let the weight labeled be y and the actual weight be x
Weight = y ± x
Maximum weight = y + x
Minimum weight = y - x

Weight = 9.4 ± 0.22
Now,
Maximum weight = 9.4 + 0.22 = 9.62 pounds
Minimum weight = 9.4 - 0.22 = 9.18 pounds

Thus, the simplified value of the maximum weight is 9.62 and the minimum weight is 9.18. Also, the function for the maximum and minimum weight is y + x and y - x

Answer:

No solutions.

Step-by-step explanation:

We are given the inequality 6(x+3) < 3(2x+6), and we want to solve the inequality for x.

We can first do the distributive property on both sides, where we multiply each term on the left side by 6, and each term on the right by 3.

6(x+3) < 3(2x+6)

6x + 18 < 6x + 18

Solving inequalities is a lot like solving equations; we want to isolate the variable by itself on one side.

First, we can subtract 18 from both sides.

6x + 18 < 6x + 18

    -18           -18

____________________

6x < 6x

Now, we can subtract 6x from both sides, to get 6x off the right side.

6x < 6x

-6x   -6x

0 < 0

We now have the inequality 0 < 0. This is never true, as 0 is always equal to 0.

Therefore, there are no values of x that will make this true, because no matter what, we will end up with a false statement. The answer is no solutions.
