Choose the correct simplification of the expression (8x2)3.

( 8x²)³ =  512 .

Step-by-step explanation:

Given : ( 8x²)³.

To find : simplification.

Solution : We have given that ( 8x²)³.

We can write it (8)³ * (x²)³.

⇒ 512 .

Therefore,  ( 8x²)³ =  512 .

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
