Find the exact value using a sum or difference identity: cos (-300°)
Hint: sin(A + B) = sin A cos
B = cos A sin B
cos(A + B) = cos A cos B = sin A sin B

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108
