Question

How do you evaluate 3x+8 when x=2?

Answer 1

Plug the x in :)

3(2) + 8
6 + 8
=14

Answer 2

Answer:

3x + 8 is equal to 14 when x = 2.

Step-by-step explanation:

To evaluate the expression 3x + 8 when x = 2, we simply subsititute the value of x into the expression.  We can write this expression as the function:

f(x) = 3x + 8

And we can evaluate the function when x = 2 by simply plugging in the value 2 for x:

f(x) = 3x + 8

f(2) = 3(2) + 8

f(2) = 6 + 8

f(2) = 14

Hence, the expression 3x + 8 is equal to 14 when x = 2.

Cheers.
