Answer:
Step-by-step explanation:
x^3 + x^2 - x + 2 \ x + 4 = x^2 -3x + 11 - 42/(x+4)
3X+11=125
3X=125-11
3X=114
X=114/3
X=38
So the answeris B 38
E=mv²
divide both sides by m
E/m=v²
square root both sides
v=√E/m
m=2,E=64
v=√64/2
v=9/√2
Length: 16
Width: 8
W + W + L + L = P
8 + 8 + 16 + 16 = 48
48 = 48
