Answer: Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x (Number of miles)
Given:
For Company A ,
Flat charge= $45
Charge per mile = 11 cents = 0.11 [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile = 13 cents = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B - Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence, Company B charges $(15.5+0.12x) more for x miles than company A.
I'm pretty sure it would be 118 but I might be wrong

Step 1) Divide 6 and 4 (the last 2 numbers) and bring everything else down
<em>6x^24x+2x+4</em>
Step 2) Place in parentheses
<em>(6x^24x)+(2x+4)</em>
Step 3) Figure out what you can take out of each parentheses.
**In the first one, you can take out 6x because both numbers have x and 6 is the largest number 6 and 24 can go into.**
**In the second one, you can only take out 2 because 2 is the largest number that goes into 2 and 4.**
Step 4) You will know you did it correctly when the parentheses match up
<em>6x(x+4) + 2(x+4)</em> <<< this is how it should look
Answer: <em>(6x+2)(x+4)</em>
