Okay so we know that side WT and side SV are the same length because of the hypotenuse leg theorem so now you just have to solve for x.
2x+9=4x-1
get the xs on one side
4x-2x=9+1
simplify
2x=10
divide by 2
x=5
Answer:
r =9
Step-by-step explanation:
7r-r=54
Combine like terms
6r = 54
6r/6 = 54/6
r =9
5/2 ....................................
Answer:
