To the nearest tenth the zeroes are:
EXPLANATION
The constant term is 2, and the coefficient of the highest degree is -5 so test all rational factors of
These are;
Good for us the very first one is a root. Therefore,
is a root. These also means that
is a factor. Therefore we perform long division to find the other factors as follows.
We can now factor the polynomial as,
This implies that,
Which gives us
Or
We complete the square to obtain,
Taking square root of both sides gives;
This implies

At 900 miles, the cost for the two rentals will be same.
Step-by-step explanation:
Given,
A+ Auto rental: $175 plus $0.10 per mile
Let,
x be the number of miles.
y be the total distance.
y = 0.10x+175 Eqn 1
Zippy Auto rental: $220 plus $0.05 per mile
y = 0.05x+220 Eqn 2
When Eqn 1 = Eqn 2, the cost will be same
Therefore;
Dividing both sides by 0.05
At 900 miles, the cost for the two rentals will be same.
