Answer:

(B)21+3a

Step-by-step explanation:

An expression is said to be distributive when:

$(a+b)c=a \cdot c+b \cdot c$

Given the algebraic expression: (7 + a)3

Applying the distributive property

$(7 + a)3 = 7 \cdot 3+a \cdot 3\\=21+3a$

An equivalent expression is 21+3a.

The correct option is B
