We have an expression and we know what the variables are equal.
We can just replace all variables with their values.
Now the expression becomes [tex]4(2)^2 - 2(7) / 7 + 2(2)[/tex].
Just use the order of operations to solve.
First, solve all exponents.
There is one exponent. Simplify.
[tex]4(2)^2 - 2(7) / 7 + 2(2)[/tex] = 4(4) - 2(7) ÷ 7 + 2(2)
Now solve all multiplication and division from left to right.
4(4) - 2(7) ÷ 7 + 2(2) =
16 - 2(7) ÷ 7 + 2(2) =
16 - 14 ÷ 7 + 2(2) =
16 - 2 + 2(2) =
16 - 2 + 4
Now do the same for addition and subtraction.
16 - 2 + 4 =
14 + 4 =
18
So, the answer is 18.
