Answer:
he would have to get an 81
Step-by-step explanation:
Foil
first
outer
inner
last
example if you had
(x+y)(z+t)
first x times z
outer x time t
inner y times z
last y times t
so
FOIL
(t+2bs^2)(2t-3bs^2)
FIRST (t times 2t=2t^2)
Outer (t times -3bs^2=-3tbs^2)
Inner (2bs^2 times 2t=4tbs^2)
Last (2bs^2 times -3bs^2=-6b^2s^4)
now add
2t^2-3tbs^2+4tbs^2-6b^2s^4
add like terms (-3tbs^2+4tbs^2=1tbs^2=tbs^2)
2t^2+tbs^2-6b^2s^4

We know that
[volume of a sphere]=(4/3)*pi*r³
for r= 3 in
calculate the volume of one <span>balloon
</span>balloons=(4/3)*pi*r³-------> (4/3)*pi*3³----------> 113.04 in³
if the rate is 200 in³ --------------------> 1 minute
113.04 in³------------------------> X
X=113.04/200------------> 0.5652
the answer is 0.6 minutes
