Step-by-step explanation:
Answer:
I think it is 6.
Step-by-step explanation:
on a parrelelogram parrelell sides r =. this means that 6x-15=x+15
we can subtract x from both sides and get 5x-15=15. add 15 to both sides and get 5x=30. Divide both sides by 5 and get x=6.
Substraction is a comutative operation
x + 3x + 4 = 72
4x + 4 = 72
4x = 68
x = 68 / 4
x = 17.

Step-by-step explanation:
roots as exponents are fractions
if there is no root number next to the radical sign its assumed that its 1/2
3√2 is 2^(1/3)
√3 is 3^(1/2)
4√3 is 3^(1/4)
5√2 is 2^(1/5)
