Answer:
the 2nd one is the answer :)
Answer:
f(x)=5x^3-2x^2-90x-36=0
=x^2(5x-2)-18(5x-2)=(x^2-18)(5x-2)=0
x^2-18=0/5x-2=0
x^2=18=x=9√2
5x-2=0
x=2/5
zeros are 9√2,2/5
356/8 = 44.5
44.5 miles/hour
44.5 miles per hour
Answer:
t = 0
Step-by-step explanation:
28 = 4t + 28
Take away 28 from both sides to make 4t by itself
28 - 28= 4t + 28 - 28
0 = 4t
Divide both sides by 4 to make t on its own
t = 0
