Plzzz help failed it 3 times already what is the answer to the following question:

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

hey i’m new i won’t be answering any questions now bye peeps see you next time

the 4th choice is the correct one

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
