Answer:

See below.

Step-by-step explanation:

For each problem, the first line below the problem is the result of factoring and is bold. If there is a second bold line below, then it's factored and simplified.

Problem 1.

5(a + 3)^2 - (a + 3) =

= (a + 3)[5(a + 3) - 1]

= (a + 3)[5a + 15 - 1]

= (a + 3)(5a + 14)

Problem 2.

p^2 - 6 - q(p^2 - 6)^2 =

= (p^2 - 6)[1 - q(p^2 - 6)]

Problem 3.

m(m + n) - 3m(m + n)^2 =

= m(m + n)[1 - 3(m + n)]

= m(m + n)[1 - 3m - 3n]

Hey there :) I'm pretty sure that your answer is D) ∠S ≅ <span>∠Y because corresponding angles of similar triangles are congruent.

I think that it is the answer because if you shift your paper around, and look at the angles from different views, you can tell that angles S and Y are congruent, or the same, because of the way that both angles are at the end of the longer sides of both triangles.

So, your answer is D!
