Answer:
x = -1
Step-by-step explanation:
8 = 2^(x + 4)
Rewriting 8 as 2^3
2^3 = 2^(x + 4)
Since the bases are the same, the exponents must be the same
3 = x+4
Subtract 4 from each side
3-4 =x+4-4
-1 =x
This is the answer :
x=–1
Choose (B)
What?
the answer is 24 m3
(-3, 3).
4x^2-36= 0
4x^2 = 36 Taking square roots of both sides:
2x = +/- 6
x = +/- 3.
