If n is 2, you substitute 2 for n and multiply 5(2)+8= 10 +8 = 18
A: -5/18
B:1 and 16/35
C: 7/30
D: 7/8
The answer is:
3
w^2 - 1 = w + 5
3^2 - 1 = w + 5
3^2 = 3(3) = 9
9-1 = 8
8 = 3 + 5
8 = 8

Copy an angle is the best solution with compass and straight edge.
Solve for y by simplifying both sides of the equation, then isolating the variable.
y = x^2/2^z - w/2z
