Answer:
a) 7x^2 + 5x
Step-by-step explanation:
(9x^2 + 8x) – (2x^2 + 3x)
Distribute the minus sign
(9x^2 + 8x) – 2x^2 - 3x
Line them up vertically
(9x^2 + 8x)
– 2x^2 - 3x

7x^2 +5x
Answer:
2 21 degree angles
Step-by-step explanation:
An isosoles triangle has two congruent angles and every triangle's sum of interior angles equals 180 degrees. 138*2>180, so the 138 degree angle cannot be congruent to any of the other angles. Therefore:
180=138+2x
42=2x
21 degrees=x
