Lets x = width
length = x + 4 (4 meters longer than wide)
A = L * W
192 = x ( x +4)
192 = x^2 + 4x
x^2 + 4x - 192 = 0
(x +16)(x-12) = 0
x - 12 = 0, x = 12
x + 16 = 0, x = -16
so width x = 12
length = 12 + 4 = 16 (4 meters longer than wide)
answer. J
16
Answer: -1
Step-by-step explanation:
because x equals to -2, thus the first term is -2 * -2 = 4.
For the second terms,^3 and the square root canceled, so you got the answer still y, which is also -5. Therefore, you add them. and you got the answer (4) + (-5) = -1
