Question

20. Determine the following product. 5g(-3g²h - 7g + 9)




A.
-15g³h - 35g² + 45g



B.
-15g³h + 35g² + 45g



C.
-15g³h + 35g² - 45g



D.
-20g³h 45g

Answer 1

Distribute 5g to all of the terms in parentheses:

$5g \times -3g^2h = -15g^3h$
$5g \times -7g = -35g^2$
$5g \times 9 = 45g$

$-15g^3h - 35g^2 + 45g$

The answer is A.
