AYUDAME DRAKE19
A) (4a² + 2ab + 5b)+(6a²-7ab)
B) (-15mn²+ 6m²n -9m) + (-13m²n-2m+3)
C) (-6x³y²+7x²y³-9) + (-8/3x³y²+7/4)

Answer 1

A) (4a² + 2ab + 5b)+(6a²-7ab)
     = 10$a^{2}$ - 5ab + 5b

B) (-15mn²+ 6m²n -9m) + (-13m²n-2m+3)
     = -15m$n^{2}$ - 7$m^{2}$n - 11m + 3

C) (-6x³y²+7x²y³-9) + (-8/3x³y²+7/4)
     = $-8 \frac{2}{3} x^{3} y^{2} + 7x^{2} y^{3} - \frac{29}{4}$
