Answer:
320 meters
Step-by-step explanation:
x² + 200x = 166400
It's a square, area should be side²
x² + 2(x)(100) = 166400
x² + 2(x)(100) + 100² = 166400 + 100²
(x + 100)² = 176400
x + 100 = 420
Since these are sides, we just consider the positive square root
x + 100 = 420
x = 320m
Answer:
Do you want the answer for all of them
Step-by-step explanation:
Answer:
A) 6
Step-by-step explanation:
-110= -2(8x+7)

Subtract both sides by 7
48 = 8x
Divide both sides by 8
6 = x
