Answer:
375/x = 125
1. 375/x = 125 -- given. You are given this information.
2. 375 = 125x -- multiplication property. You are multiplying each side by x to cancel it out as a denominator.
3. 375/125 = 125x/125 -- division property. You are dividing each side by 125 to isolate x.
x = 3
It takes 9 seconds to hit the ground.
Setting the equation equal to 0, we have:
0 = 144 + 128t - 16t²
Factoring out the GCF, we have
0 = 16(9 + 8t - t²)
Factoring out -1, we have:
0 = -16(-9 - 8t + t²)
In standard form, this is
-16(t² - 8t - 9) = 0
This is easily factorable; -9(1) = -9 and -9+1 = -8:
-16(t-9)(t+1) = 0
Using the zero product property, we know either t-9=0 or t+1=0; therefore t=9 or t=-1. Since negative time makes no sense, t=9.
