Answer:
P = 8x + 2 When X is 12, P is 98 m
Step-by-step explanation:
P = 2(L + W)
P = 2[(2x - 5) + (2x + 6)]
P = 2[4x + 1]
P = 8x + 2
P = 8(12) + 2
P = 98 m
x<52
I added 21 to both sides
256
64(15-1x2-9)
64(15-2-9)
64 x 4
if you wanna find x
fx)=x
please give more details
√13 + 3 = x
-√13 + 3 = x
y = x² - 6x - 4
0 = x² - 6x - 4
0 + 13 = x² - 6x - 4 + 13
13 = x² - 6x + 9
13 = (x-3)²
±√13 = x-3
±√13 + 3 = x
