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 ive asked this like 3 times now so someone

w^ 2 - v + 1

(-2)^2 -(-8) +1

Choice D

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
