Answer:

10x^3+14x^2-25x-35

Step-by-step explanation:

f(x) = 2x^2 -5

g(x)= 5x+7

f(g(x)) = (2x^2 -5)(5x+7)

5x(2x^2 -5)+7(2x^2 -5)

10x^3-25x+14x^2-35

10x^3+14x^2-25x-35

Answer:

$9C=5(F-32)$

Step-by-step explanation:

The equation which can convert the temperature from degree Celsius into degree Fahrenheit is given as under

$9C=5(F-32)$

We can solve it further for F as

$9C=5F-5 \times 32$

$9C=5F-160$

$9C+160=5F$

Dividing both sides by 5 we get

$\frac{9C}{5}+32=F$

$F=\frac{9C}{5}+32$

Now substituting values of C in this equation will give us the corresponding values of F

Ex : C=1

$F=\frac{ 9\times 1}{5}+32$

$F=\frac{ 9+160}{5}$

$F=\frac{ 169}{5}$

Hence 1 degree Celsius is $\frac{ 169}{5}$ degree Fahrenheit

The volume of a rectangular prism has 5376 cubic inches the prism is 14 in long and 16 in wide how tall is the prism

Mkey [24]

Answer:

The height of the prism is $24\ in$

Step-by-step explanation:

we know that

The volume of the rectangular prism is equal to

$V=LWH$

In this problem we have

$V=5,376\ in^{3}$

$L=14\ in$

$W=16\ in$

substitute in the formula and solve for H

$5,376=(14)(16)H$

$H=5,376/[(14)(16)]$

$H=24\ in$

Rashid [163]

Answer:

$a = 8n + 6$

Step-by-step explanation:

<u>Step 1: Distribute</u>

<u /> $a = 14 + (n - 1)(8)$

$a = 14 + (8 * n) + (8 * -1)$

$a = 14 + 8n - 8$

$a = 8n + 6$

Answer: $a = 8n + 6$
