Recall that in a rhombus, the diagonals bisect each other, namely, they make twin angles at each of the vertices, thus check the picture below.
make sure your calculator is in Degree mode.
(5x + 3y)(x - 5y)
5x*x = 5x2
5x*-5y = -25xy
3y*x = 3xy
3y*-5y = -15y2
= 5x2 - 22xy - 15y2
X=11/5 x=2.2 is slicing for x
2(2 1/2 + 1 3/4) =
2(5/2 + 7/4) =
2(10/4 + 7/4) =
2(17/4) =
34/4 =
8 1/2 cups in total are needed <==
