Answer:
X = 102
Step-by-step explanation:
41 + 37 + x = 180
78 + x = 180
X = 180 - 78 = 102
P = L + L + w + w
72 = 2(L) + 2(L-4)
Distribute
72 = 2(L) + 2(L) - 8
Add like terms
72 = 4(L) - 8
Subtract 8 from both sides
64 = 4(L)
Divide both sides by 4
16 = L
The length is 16. Now substitute that in the equation for finding w.
w = L - 4
w =
Answer:
I dunno what you wrote at the top, but I solved the picture
Step-by-step explanation:
Its line 1
if we expand the second and third expressions they come back to the first.
The last one is called the vertex form of a parabola
160•.60=96
160-96=64
the discount is 96 and the amount after the discount is 64 i think
