Answer:
c. 14q²-2q+14/3
Step-by-step explanation:
9q²-2/3(3q-7)+5q²
multiply 2/3 with bracket
= 9q²-2q+14/3+5q²
=14q²-2q+14/3
C
Given
9q² - [tex]\frac{2}{3}[/tex](3q - 7) + 5q² ← distribute parenthesis by - [tex]\frac{2}{3}[/tex]
= 9q² - 2q + [tex]\frac{14}{3}[/tex] + 5q² ← collect like terms
= 14q² - 2q + [tex]\frac{14}{3}[/tex] → C
