Answer 3

To evaluate the expression 6x + 4(2x + 7) when x is equal to 3, we substitute the value of x into the expression and simplify:

Let's substitute x = 3:

6(3) + 4(2(3) + 7)

First, we simplify the inner parentheses:

6(3) + 4(6 + 7)

Next, we simplify the multiplication inside the parentheses:

6(3) + 4(13)

Now, we multiply:

18 + 52

Finally, we add:

18 + 52 = 70

Therefore, when x is equal to 3, the expression 6x + 4(2x + 7) evaluates to 70.
