3 (7 + x2); x = 2 (x is squared by 2) (evaluate each expression for the given values of the variables)

33

Step-by-step explanation:

This is a substitution question, so to solve you will have to substitute ... substitution question is when a specific number is given replace a certain number

Back to the question, 3 (7+x2)

And x is given to be 2

So let's continue by substituting the value of x into the equation

3 (7+2^2)

3 (7+4)

3 (11)

33

The final answer is 33

Hope you understand how we get our final answer, just follow the step above
