Answer:

x = -4

Step-by-step explanation:

<u>Solve for x</u>

5 ( x + 7 ) = 15

Divide each side by 5

5( x + 7 ) ÷ 5 = 15 ÷ 5
x + 7 = 3

subtract 7 from both side

x + 7- 7 = 3 - 7
x = -4

Answer:

$10x^{3} - 26x^{2} - 12x$

Step-by-step explanation:

1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.

$10x^{3} - 30x^{2} + 4x^{2} -12x$

2) Collect like terms.

$10x^{3} + (-30x^{2} +4x^{2} )-12x$

3) Simplify.

$10x^{3} - 26x^{2} -12x$

Therefor, the answer is, 10x^3 - 26x^2 - 12x.
