Question

Use the Distributive Property to write each expression as an equivalent algebraic expression. (7 + a)3 Question 4 options: 3(7a) 21 + 3a 10 + 3a 7 + 3a

Answer 1

(B)21+3a

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
