That is a difference of two square numbers, we can factorize them easily:
<span>0 =-b^2 + 25
b^2 - 25 = 0
(b + 5)(b - 5) = 0</span>
Answer:
x = 20
y = 8
In a parallelogram, there are always two pairs of equal sides, where in this question:
Side CD = Side BA
Side DA = Side CB
Use this to find x and y.
CD = BA
15 = x - 5
x = 20 (rearranging to find x)
DA = CB
y = 8
It’s 362.50 you just add 145 for the 100% and get 290 then for the 50% you just divide 145 by two and get 72.50 so you add them together at get 362.50
