Question

1. Evaluate the expression, 3x(4+ x), when x = 2.​

Answer 1

3x(4+x) when x=2 is 36

Explanation:

3x(4+x) and x=2

Plug in 2 for every x and simplify:

(3(2))(4+(2))
6(6)

Now multiply:
6*6=36

Answer 2

= 36

Explanation:

Let us substitute x=2 to the equation: 3x(4+ x)

-

3(2)(4+ (2))

6*6 =36
