Question

pls fast it's so urgent​

Answer 1

1. 3x + 7x = 10x

2. 3x² + (-4x²) = 3x² - 4x² = -1x²

3. -8ab + 11ab = 3ab

4. (-10xy) + (-2xy) = -10xy -2xy = -12xy

5. 16ab + (-9ab) + 10ab = 16ab - 9ab + 10ab = 17ab

Answer 2

Step-by-step explanation:

3x + 7x = 10x

3x^2 + (-4x^2) = 3x^2 - 4x^2 = -1x^2

-8ab + 11ab = 3ab

(-10xy)+(-2xy) = -10xy -2xy = 12xy

16ab +(-9ab)+10ab = 17ab
