Answer:

x³+8

Step-by-step explanation:

(x − a)(x^2 +ax + a^2)

a=2

Substitute a for 2 in the algebraic expression

(x − 2)(x^2 +2x + 2^2)

(x − 2)(x^2 +2x + 4)

Multiply (x^2 +2x + 4) by (x-2)

x(x^2 +2x + 4)-2(x^2 +2x + 4)

x³+2x²+4x-2x²-4x-8

Collect like terms

x³+2x²-2x²+4x-4x+8

x³+8

nydimaria [60]

Answer:

Step-by-step explanation:

(15x + 5) and (-2 + 16x) represents the measures of corresponding angles.

Measures of corresponding angles are equal.

Therefore,

- 2 + 16x = 15x + 5

16x - 15x = 5 + 2

x = 7
