Answer:
what do you need help with
Step-by-step explanation:
I think it is only the first and third boxes
A = LW
A = 120
W = L - 2
120 = L(L-2)
120 = L^2 - 2L
L^2 - 2L - 120 = 0
(L - 12)(L + 10) = 0
L - 12 = 0
L = 12
L + 10 = 0
L = -10 (extraneous solution...will not work)
length (L) = 12 ft
width (W) = L - 2 = 12 - 2 = 10 ft
Step-by-step explanation:
any inequality with an "or equal" condition.
because that means the points on the boundary line are included, and then we draw it as a solid line.
so, it seems the 4th answer is such a case.
Answer:
Since slope of line y = 0 and y = 4
Step-by-step explanation:
Given:
y = 4
Computation:
Equation of slope;
y = ax + c
So,
y = (a)(0) + 4
Since slope of line y = 0 and y = 4
