The integer 8 represents a gain of 8 yards.
F(x)=-5t^2+20t+60
Divide everything by -5
f(x)=t^2-4t-12
(t-6)(t+2)
Set it up to zero
t-6=0. t+2=0
t=6. t=-2
Since you can’t have negative seconds, the answer is 6 seconds
The answer is 4x^2
all you gotta do is multiply them like usually but -
(2X^3.)(2X^-1)
4X^(3-1)=4X^2

Step-by-step explanation:
geometry is the worst. but i have a way to remember how to find the area. (Apple Pies are too --> A=πr^2 --> area = pie×radius^squared) so basically you sub in 78.5 in for area and then you solve for r.
Hope i helped kinda lol
