A²+b²=c²

12²+35²=c²

144+1225= c²

c²=1369

c=√1369

c=37

The aim here is to get all of the x's onto one side and the numbers onto the other side:

We can start by subtracting x from each side

2x+11=1

We can then subtract 11 from both sides

2x=-10

Finally, we can divide both sides by 2 leaving us with:

x = -5

Combine like terms.

3x + 4x -5 -2

7x - 7

**Answer:**

Gretchen because a 1/5 is bigger than 1/8 so 3/5 is bigger than 3/8

Since it could drive 49 miles on 1 gallon, and this is also it's gas mileage, (because 490/10=49) it could drive 45 times more on 45 gallons than on one. So, we multiply 45 by 49 to get 2209 gallons on 45 gallons of gas.
