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

(B)21+3a

Step-by-step explanation:

An expression is said to be distributive when:

Given the algebraic expression: (7 + a)3

Applying the distributive property

An equivalent expression is 21+3a.

The correct option is B

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
