Answer:
A
Step-by-step explanation:
You have to use Pythagorean theorem.
a^2 + b^2 = c^2
x^2 + 3^2 = 5^2 (you know that b=3 because is the half of 6)
x^2 + 9 = 25
x^2 = 25 - 9
x^2 = 16
x = √16
x = 4
2⁻³² = (-2²)⁻⁶ • (2⁻⁵)⁻⁴
2⁻⁵ = (2²)² • (2³)⁻³
2⁸ = (-2⁻⁴)⁻² • (2²)⁰
1 = 2⁴ • (2²)⁻²
x=-5, y=2 and z=0
-8(2x +x )/-2y =(-8•3x)/-2y = [-8•3(-5)] / (-2•2) = 120/(-4) =-30
