Answer:
-9 = a
Step-by-step explanation:
Divide both sides by -4 to isolate a: a = -36/4 = -9 = a
The volume in the same in both cynclinders would be my guess
Imagine a 'U' shape
sides are x legnth
base is b legnth
2x+b=25
area is height times base=xb
xb=50
2x+b=25
solve
minus 2x both sides
b=25-2x
sub for b
x(25-2x)=50
25x-2x^2=50
times -1 both sides
2x^2-25x=-50
add 50 both sides
2x^2-25x+50=0
use quadratic formula or something
x=2.5 or 10
A is the answer
