Answer:
Step-by-step explanation:
Formula
A = L * W
Givens
W = W
L = W + 2
Solution
Area = L*W
Area = (W+2)*W = 80 Remove the brackets.
Area = W^2 + 2W = 80 Subtract 80 from both sides.
Area = w^2+2W-80=80-80 Combine
Area = w^2 +2W-80 = 0 Factor.
Area = (w+10)(w - 8) = 0
W + 10 = 0 won't work
W = - 10 which isn't possible
W- 8 = 0
W = 8
L = 8 + 2 = 10
The answer looks like A
Answer:
![x = y^3+5y](https://tex.z-dn.net/?f=x%20%20%3D%20y%5E3%2B5y)
Step-by-step explanation:
Complete question
![\frac{x - 5y}{y^3} - 1=0\\](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20-%205y%7D%7By%5E3%7D%20-%201%3D0%5C%5C)
Required
Solve for x
We have:
![\frac{x - 5y}{y^3} - 1=0](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20-%205y%7D%7By%5E3%7D%20-%201%3D0)
Collect like terms
![\frac{x - 5y}{y^3} = 1](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20-%205y%7D%7By%5E3%7D%20%3D%201)
Multiply through by ![y^3](https://tex.z-dn.net/?f=y%5E3)
![x - 5y = y^3](https://tex.z-dn.net/?f=x%20-%205y%20%3D%20y%5E3)
Make x the subject
![x = y^3+5y](https://tex.z-dn.net/?f=x%20%20%3D%20y%5E3%2B5y)
Answer:
what are you talking about the picture is not there
Step-by-step explanation:
Well the displacement of milage from the 2 places if 75km however, the women and her car are in the same place so there is no displacement. But 75km is the correct mathematical answer.
Maybe you meant solve for x?
If so, the answer is 4
