Question

Simplify the expression. 3(2x + 5) - 3x A. 3x + 15 B. -3x + 15 C. 3x + 5 D. -3x + 5

Answer 1

`\sf \: 3x + 15`

Explanation:

Given expression,

→ 3(2x + 5) - 3x

Let's simplify the expression,

→ 3(2x + 5) - 3x

→ 3(2x) + 3(5) - 3x

→ 6x + 15 - 3x

→ (6x - 3x) + 15

→ 3x + 15

Hence, the answer is 3x + 15.

Answer 2

To simplify the following expression:

`3(2x+5)-3x`

As a first step, we are going to apply distributive property of multiplication:

`6x+15-3x`

then, simplify like terms:

`3x+15`
