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:
c=0
Step-by-step explanation:
x² + 11x + 0 = y
x² + 11x + 0 = 0
U already know that y=0 by looking at the equations above,
But your worksheet never state "c", so we will take that c is 0 (look at the equations above.)
So c is just 0.
Answer: A and D
Explanation -
Parallel lines have the same slope
S+(2+1/2)s+20=48
2/2s+5/2s=48-20
7/2s=28
7s=28*2=2(20+8)=40+16
7s=56
s=56/7
s=8
