(x+3)^2 when tking the square root of both sides of this equation how many solutions will it have

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

I’m still confused on how to work the percentages

Find the value of x in each case. give reasons to justify your solutions! d q ∈ pr
