Please help me!! Which could be the first step in simplifying this expression? Check all that apply. (x^3x^-6)^2

□(x^-18)^2
□(x^-3)^2
□(x^-2)^2
□x^5x^-4

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

answer is 1
