Answer:

p = -7

Step-by-step explanation:

7(p+3) = -28

now we times the inside of the parenthese by 7

7p+21 =-28

now we minus 21 on both sides

7p= -49

now divide

p = - 7

Answer:

-7

Step-by-step explanation:

7(p+3) = -28

Divide by 7

7(p+3) / 7 = -28 / 7

p+3 = -4

Subtract 3

p+3 (-3) = -4 (-3)

P = -7

Ara has a cube with side lengths of 4.2 cm. Which is the best estimate of the volume of the cube?

garik1379 [7]

4.2³ = 74.088. If the 4.2 is accurate, this is actually not an estimate but an exact answer. You can of course round it to 74, then it becomes an estimate.

If F(x)=4x-1 and g(x)=x^2+7, what is g(f(x))

VashaNatasha [74]

Answer

$g(f(x)) = = 16 {x}^{2} - 8x + 8$

step by step Explanation

The functions given are

$f (x)= 4x- 1$

$g(x)= {x}^{2} + 7$

We want to find:

$g(f (x))= g( 4x- 1)$

This implies that

$g(f (x))= ( (4x- 1)^{2} + 7)$

Let us now simplify

$( {a - b)}^{2} = {a}^{2} -2ab + {b}^{2}$

This implies that

$( (4x- 1)^{2} + 7) =( {(4x)}^{2} - 2(4x) \times 1 + 1$

Combine the terms to get,

$= 16 {x}^{2} - 8x + 1 + 7$

$= 16 {x}^{2} - 8x + 8$
