Answer:

we conclude that:

[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}=\frac{1}{2p^3-p^2}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]

[tex]=\frac{2p}{4p^2-1}\times \frac{6p+3}{6p^3}[/tex]

[tex]=\frac{2p}{4p^2-1}\times \frac{2p+1}{2p^3}[/tex]

[tex]\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]

[tex]=\frac{2p\left(2p+1\right)}{\left(4p^2-1\right)\times \:2p^3}[/tex]

cancel the common factor: 2

[tex]=\frac{p\left(2p+1\right)}{\left(4p^2-1\right)p^3}[/tex]

cancel the common factor: p

[tex]=\frac{2p+1}{p^2\left(4p^2-1\right)}[/tex]

[tex]=\frac{2p+1}{p^2\left(2p+1\right)\left(2p-1\right)}[/tex]

cancel the common factor: 2p+1

[tex]=\frac{1}{p^2\left(2p-1\right)}[/tex]

Expanding

[tex]=\frac{1}{2p^3-p^2}[/tex]

Thus, we conclude that:

[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}=\frac{1}{2p^3-p^2}[/tex]

Answer:

$1.96

Step-by-step explanation:

Let's set up a proportion:

1 lb : $4.25 = 0.46 lb : $x

Here, x is the cost of 0.46 pounds. The ratio above can also be written in fraction form as:

[tex]\frac{1}{4.25} =\frac{0.46}{x}[/tex]

Now, we cross-multiply:

1 * x = 4.25 * 0.46

x = 1.955 ≈ $1.96

Answer:

[tex]x-3y=21[/tex]

Step-by-step explanation:

The standard form of a linear equation is [tex]Ax+By=C[/tex]

STEP 1: Multiply both sides by [tex]3[/tex].

STEP 2: Simplify [tex]3(y+6).[/tex]

STEP 3: Simplify again.

STEP 4: Rewrite the equation with the sides flipped.

STEP 5: Move all terms containing variables to the left side of the equation.

STEP 6: Move all terms not containing a variable to the right side of the equation.

Rearranging the equation given to conform with the standard form of an equation, the expression becomes -x + 3y = - 21

The standard form of expression a linear equation is given as :

Given the expression : y + 6 = 1/3(x - 3)

Multiply both sides by 3

3(y + 6) = x - 3

3y + 18 = x - 3

Move x and y to the same side and the constant to the other.

3y - x = - 3 - 18

-x + 3y = - 21

Hence, the standard form of the equation is - x + 3y = - 21

Step-by-step explanation:

Given

We have to determine [tex]g\left(x\right)\:-\:h\left(x\right)\:=\:2x^2\:-\:3x[/tex]

so

[tex]g\left(x\right)\:-\:h\left(x\right)\:=\:2x^2\:-\:3x[/tex]

Thus we conclude that:

Answer:

12:24 = 1:2

Step-by-step explanation:

Since there are 12 multiplication problems, and 24 division problems, the ratio of multiplication and division problems are 12:24, now we need to put it in simplest form.

We need to find the highest number of which both are divisible by, 12 and 24 are both divisible by 12.

So 12÷12 = 1, and 24÷12 = 2, so 12:24 in simplest form is 1/2 or 1:2.

Answer:

1/2

Step-by-step explanation:

12 is half of 24. Therefore, the answer as a fraction in simplest form is 1/2.

Step-by-step explanation:

I am assuming you want to solve this>

Solve 2x ³ + x ² -7x - 6​ = 0

It looks like x = -1 is a solution so we try it:

2*(-1)^3 + (-1)^2 -7(-1) - 6

= -2 + 1 + 7 - 6

= -1 + 1 = 0

So x = -1 is one root.

So (x + 1) must be a factor of P(x)

Now we divide by x + 1:

x + 1)2x ³     + x ²   -7x -  6​( 2x^2 - x - 6  <--- quotient

       2x^3 + 2x^2

                  -x^2  - 7x

                  -x^2  -  x

                             -6x -  6

                             -6x -  6

                              ----------

2x^2 - x - 6 = 0

(2x + 3)(x - 2) = 0

x = -1.5, 2.

Reagan needs to sew a 1346 centimeters fringe around the edge of the bed spring.

Given that, Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters.

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Now, the perimeter = 2(238+435)

= 2×673

= 1346 centimeters

Therefore, Reagan needs to sew a 1346 centimeters fringe around the edge of the bed spring.

x=6

MKL=37

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. because U is between T and B

TU +UB = TB

2x+3x+1 =21

5x = 20

x= 4

mTU = 2x = 2*4 = 8

mUB = 3x+1 = 3*4 +1 = 12 +1 = 13

2.

m∠JKL = 59°

m∠MKL + m∠JKM = m∠JKL

5x+7 +2x+10 = 59

7x +17 = 59

7x = 59-17

x = 42/7 = 6

m∠MKL=5x+7 = 5*6 +7 = 30+7 = 37°

Answer:

The remainder is 10

Step-by-step explanation:

The find the remainder when f(x) divided by g(x), find the value of x when g(x) = 0, then substitute it in f to find the value of the remainder

∵ f(x) = 3[tex]x^{5}[/tex] + 2[tex]x^{4}[/tex] + 5

∵ f(x) is divided by x - 1

∴ g(x) = x - 1

→ Equate g(x) by 0 to find x

∵ g(x) = 0

∴ x - 1 = 0

→ Add 1 to both sides

∵ x - 1 + 1 = 0 + 1

∴ x = 1

→ Substitute x in f by 1

∵ f(1) = 3[tex](1)^{5}[/tex] + 2[tex](1)^{4}[/tex] + 5

∴ f(1) = 3(1) + 2(1) + 5

∴ f(1) = 3 + 2 + 5

∴ f(1) = 10

∵ The remainder is the value of f(1)

∴ The remainder is 10
