Answer:
Step-by-step explanation:
Let us apply the distributive property to find an equivalent expression for:
For all real numbers a, b, and c, the distributive property says that:
We apply this property to get:
We simplify the RHS to get:
$2.70
2.25*1.2 = 2.7
Replace the x in 7x by (3x + 1):-
(f o g)(x) = 7 * (3x + 1)
= 21x + 7 which is choice D.
