Me with this

triangle abc is dilated so that the side lengths of the image are three times the lengths of their corresponding sides. which of the following statements are true?
select all that apply.

ab ≅ a'b'
cb ~ c'b'
∠a ≅ ∠a'
ca ≅ c'a'
∠b ~ ∠b'

Since all the sides would be scaled together, all the angles would still be similar.

The answer should be:

∠A ≅ ∠A'

∠B ~ ∠B'

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
