Answer:

Step-by-step explanation:
Let
be the number of gallons so
is the number of miles traveled per
gallons.
We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by
, his car will travel a total distance of 25g (where g is the number of gallons.
We also know that the total distance is given by
, so we can put the two expressions together to get our function:

Let's check:
- If he uses 1 gallon (g=1), so

miles
He will travel 25 miles with one gallon.
- If he uses 2 gallons (g=2), so


He will travel 50 miles with two gallon.
Answer:
$4.50/ g - Games
Step-by-step explanation:
$18
------------- = $4.50/g
4 g
$27
------- = $4.50/g
6 g
C(x) = ($4.50/game)x, where x is the # of games played.
Answer:
(7w + 9x)(7w - 9x)
Step-by-step explanation:
Given expression;
49w² - 81x²
Now to solve the problem;
49w² - 81x² = 7²w² - 9²x²
Using differences of two squares;
x² - y² = (x + y)(x - y)
So;
7²w² - 9²x² = (7w + 9x)(7w - 9x)
