Xy = 216
x = 216/y
2x + 2y = 60
2(216/y) + 2y = 60
432 + 2y^2 = 60y
2y^2 - 60y + 432 = 0
y = 18 , y = 12
if y = 12
x = 216/12
x = 18
length = 18
width = 12
Answer:
Step-by-step explanation:
3² * 5³ = 3*3 * 5*5*5
= 9 * 125
= 1125
Thank you for your question!
Your really close!
Just set this up as an algebraic equation:
4x - 10 = 30
4x = 40
x = 10
Hope this helped!
Given ,
8(6b+3) =0
=> 48b+24=0
=> b= -24/48
=> b = -3/4
