= 4x^2 + 3x + 8 + 12x^2 - 8x + 17
= 16x^2 - 5x + 25 songs.
Subtract what she deleted:-
= 16x^2 - 5x + 25 - (2x^2 - x + 4)
= 16x^2 - 5x + 25 - 2x^2 + x - 4
= 14x^2 - 4x + 21 songs Answer (Option b)
9-5y , o tambien puede ser -y-1

The two triangles are similar.
The angles of a triangle sum to 180°. Using the known angles in the first triangle, we find the missing angle measure:
180-(65+70) = 180-135 = 45
We do the same for the second triangle:
180-(65+45) = 180 - 110 = 70
Any two triangles that have all 3 angles congruent is similar by AAA.
