v^2 = 2w - x^2. w = 40; x = 4. Find the value of v.

Firstly, we can put the values given in the question into our equation.v2 = 2w - x2Goes to ...v2 = 2(40) - (4)2After we do the multiplication and indices, the equation looks like this.v2 = 80 - 16Do the subtraction.v2 = 64Now, to get rid of the squared sign, we have to do the opposite to both sides of the equation. We must square root both sides./v2 = /64Do the square roots.v = 8And you have your answer!
