If w = -2 and v = -8, which of the following expressions shows the values correctly substituted in for the variables in the expression w^2 - v + 1? -2^2 - (-8) + 1 -2^2 - 8 + 1 (-2)^2 - (8) + 1 (-2)^2 - (-8) + 1 Please help!!! <3

Hello there! :)

The last option.

Step-by-step explanation:

If w = -2 and v  = -8:

Substituting these into the equation w² - v + 1 would look like:

(-2)² - (-8) + 1

When finding the square of a negative number, parenthesis must be used because:

-2² = -4, whereas (-2) = 4.

When subtracting a negative number, parenthesis also need to be used:

-(-8) = +8.

The corresponding equation that is equivalent to this is the final equation listed, or the fourth option.
