Answer:
f(x) = 0.5x + 15
Step-by-step explanation:
Here, we want to get the total charge
From the question;
we have a flat rate of $15
now, $0.5 per mile for x miles will be a charge of 0.5 * x = $0.5x
We now add this to the flat fee to get the total score
That will be;
f(x) = 15 + 0.5x
Answer:
225/4
Step-by-step explanation:
When you are trying to find the number to be added to a binomial of the form : 
in order to make it a perfect square trinomial, all you need to do is to use the square of half of the coefficient b. That is : 
.
In your case this is: 
I’m assuming that x2 means x squares because that’s what it looks like. Correct me if I’m wrong. But anyways, (x+7)(x+3) is the answer
Do 2/5+5/7 and there's your answer. 2/5+5/7=14/35+25/35=39/35=1 4/35. :)
