What are the solutions to the equation below? (5x + 40)(4x - 24) = 0 a. x = 8 and x = -6 b. x = 40 and x = -24 c. x = 24 and x = -40 d. x = -8 and x = 6

7. if the value of x varies directly with the value of y, and x = 3 when y = 21. what is the valu y, and x = 3 when y = 21. what is the value of x when y = 105?

Prove sin2a + cos2a - 1 / sin2a + cos2a + 1 = 1 - tana / 1 + cota

Rewrite so the subject can be y in the formula d=m-y/y+n
