$7(x+4) =9(x -2) \\
7x+28=9x-18\\
2x=46\\
x=23$

7(x+4) = 9(x-2)
7x+28 = 9x-18
28+18 = 9x-7x
46 = 2x
46/2 = x
<u>23 = x</u>

What does -4(-8x-8) equal?

slavikrds [6]

Answer:

Lets break it down

( -8 x -8 ) = 64, because a negative x negative always equals a positive

-4 x 64 = -256, because a negative x positive always equals a negative

Your answer is -256.

I hope this helps!

$\huge \bf༆ Answer ༄$

Let's simply ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 5 {x}^{2} (4x - 6 {x}^{2} - 3)$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:( - 5x {}^{2} \times 4x) - ( - 5 {x}^{2} \times 6 {x}^{2} ) - ( - 5 {x}^{2} \times 3)$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 20 {x}^{3} - ( - 30 {x}^{4} ) - ( - 15 {x}^{2} )$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 20 {x}^{3} + 30 {x}^{4} + 15 {x}^{2}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:30 {x}^{4} - 20 {x}^{3} + 15 {x}^{2}$
