<h3>I’ll teach you how to solve 5x^3 - 3x^2 - 14x</h3>
--------------------------------------------------------
5x^3 - 3x^2 - 14x
Factor out the common term x:
x(5x^2 - 3x 14)
Factor 5x^2 - 3x 14:
Break the expression into groups:
(5x62+7x)+(-10x-14)
Factor out x from 5x^2+7x:
x(5x+7)
Factor out -2 from -10x-14:
-2(5x+7)
x(5x+7)-2(5x+7)
Factor out the common term 5x+7:
(5x+7)(x-2)
x(x+7)(x-2)
Your Answer Is x(x+7)(x-2)
Plz mark me as brainliest :)
The ball hits the ground when the height h(t) = 0 , so
-16t^2 + 80t = 0
-16t(t - 5) = 0
t- 5 = 0 or -16t^2 = 0 ( here t = 0 which corresponds to when ball is thrown)
t - 5 = 0 gives:-
t = 5 seconds (answer)
47.5 dollars because a is 2.75 and n is 10
