Question

Evaluate the expression for x = 4:

6 + (10 - x)^2 - 20

Answer 1

Well, if x = 4, then we can substitute that information into the given equation:
6 + (10 - x)^2 - 20.

Let us solve, shall we?

6 + (10 - x)^2 - 20 -Given Equation
6 + (10 - 4)^2 - 20 -Substitute in (x = 4)
6 + (6)^2 - 20 -Solve within the brackets
6 + 36 - 20 -Get rid of the (6)^2

And we know that (6 + 36 - 20) is equal to 22.

Best of luck to you! ^_^
