3√32x^4z
= 3√(2^5)* x^4 *z
(Square rooting the terms)
= 3*2*2*x*x√2*z
=12x^2√2z
Your answer would be A 1040.
You’re answer would be x=7
Answer:
a. steve
b. temperature
c. table
d. tony
Step-by-step explanation:
The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since 80 = 5 · 16
5 ( x² + 8 x + 16 ) = 94 Answer : B )
After that we will continue like this:
5 ( x + 4 )² = 94
( x + 4 )² = 18.8 ... etc
