Answer:
15.6

Answer:
Your answer would be D.-12
Step-by-step explanation:
Answer:
(x + 7)3y = 3xy + 21y
Step-by-step explanation:
Expand the expression in the question by using the distributive property. This means you multiply the term (number) outside the bracket with each of the terms (numbers) inside the bracket.
(x + 7)3y Expand this
= (x)(3y) + (7)(3y) Multiply 3y with x and 7
= 3xy + 21y Simplified, final answer
