Answer:
40
Step-by-step explanation:
8 and 5 are factors of 40. (8 x 5 = 40)
X*y=72
x = 5y-2
x=72/y
72/y=5y-2
72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18
(18,4)
Answer:
n=

1.047198r2
Step-by-step explanation:
Step 1: Flip the equation.
1.047198nr2=v
Step 2: Divide both sides by 1.047198r^2.
1.047198nr2
1.047198r2
=
v
1.047198r2
n=
