Question

Expand and simplify 2(x+7)+3(x+1)

Answer 1

Answer:

2(x + 7)+3(x + 1) = 5x + 17

Step-by-step explanation:

We know that a (b + c) = ab + ac

2 (x + 7) = 2 (x) + 2 (7)

= 2x + 14 ------- (1)

3(x + 1)= 3(x) + 3 (1)

= 3x + 3 ------ (2)

Given: 2(x+7)+3(x+1)

2(x + 7)+3(x + 1)

= 2x + 14 + 3x + 3 [from (1) and (2)]

= 2x + 3x + 14 + 3

= (2 +3)x + (14+3)

= 5x + 17

So, 2(x + 7)+3(x + 1) = 5x + 17
