Answer:
1-2y+y^2
Step-by-step explanation:
(1–y)^2
(1-y) * (1-y)
FOIL
first: 1*1 =1
outer: 1*-y = -y
inner: -y *1 = -y
last: -y*-y = y^2
Add together: 1+-y-y+y^2
1-2y+y^2
I don’t really know but try a calculator
4x+1=2x+7
-1 -1
4x=2x+6
-2x -2x
2x=6
2x/2- 6/2
X=3
13.13? If it is, it would be 91.91. If it's really 1313 you would need 9191 cups.
