<h3>Answer: 33</h3>
=====================================
Work Shown:
8^(x+7) = 32^(x-9)
(8)^(x+7) = (32)^(x-9)
(2^3)^(x+7) = (32)^(x-9) .... replace 8 with 2^3
(2^3)^(x+7) = (2^5)^(x-9) .... replace 32 with 2^5
2^(3(x+7)) = 2^(5(x-9)) ... multiply exponents
3(x+7) = 5(x-9) ...bases are the same, exponents are the same
3x+21 = 5x-45
21+45 = 5x-3x
66 = 2x
2x = 66
x = 66/2
x = 33
Answer:
x = 3
Step-by-step explanation:
No worries.
Perimeter = 2x width + 2x height
66 x 2 = 132
338 - 132 = 206
206 / 2 = 103
The length is 103 meters.
