Answer:
22x + 99
Step-by-step explanation:
Given
9(2x + 9) + 2(2x +9) ← factor out (2x + 9) from each term
= (2x + 9)(9 + 2)
= 11(2x + 9) ← distribute parenthesis
= 22x + 99
Here's two ways you can solve this exercise: you can expand the multiplications and sum like terms:
[tex]9(2x+9)+2(2x+9) = 18x+81+4x+18 = 22x+99[/tex]
Or you can factor the parenthesis:
[tex]9(2x+9)+2(2x+9) = (2x+9)(9+2) = 11(2x+9) = 22x+99[/tex]
