Evaluate the expression below when x = 8. If needed answer as a fraction or a decimal x^2 + 8
4x
When x = 8, we can evaluate each expression:
x^2 = 8^2 = 64
4x = 4 * 8 = 32
Now we can substitute these values back into the given expression:
x^2 + 8 = 64 + 8 = 72
Therefore, when x = 8, the expression evaluates to 72.
