Hey! Your answer for this is

7x^2 + 3x^2 = 10x^2

-2x + 15x = 13x

9 - 4 = 5

Hence, 10x^2 + 13x + 5.

Hope this helps!

Mkey [24]

Answer:

I don't believe so because congruent shapes are exactly the same but a side measurement could be the same on a square and a triangle but those aren't congruent shapes
