(1 + 2g)(7)

just need it simplified

Restrictions on f(x) = 1/x+5 and g(x) = x-2

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2. after how many seconds will the ball hit the ground before rebounding?

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
