I need help can one of yall get Solving One-Step Equations 1 anwser key plz

answer4 to the second power is 16

and 4 to the third power is 64,

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

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
