Am I supposed to be figuring out what the length of the two other legs are?
Here are the pictures of the steps I took when solving it as well as the answer to what X is
Answer:
648
Step-by-step explanation:
You can use a calculator or break it into smaller problems, then add them together
Step-by-step explanation:
x+13÷2×2=4×2
x+13=8
x+13-13=8-13
x=8-13
x=-5
Expand the brackets first
5(wx-v) = 9(x + v)
5wx - 5v = 9x + 9v
Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v
factorise out the x
x(9-5w) = 14v
then divide by 9-5w
x = 14v/(9-5w)
