9. The painter bought 8 cans of paint for $12.99 each. How much did he spend on paint?

So I think we have to first figure out how many gallons is each coat of paint.

Bigger room: 3 coats paint.

Smaller room: 2 coats paint.

Total here is 5 coats of paint, and it's for 8 gallons, so each coat is 1.6 gallons (8/5).

So 1 coat of paint = 1.6 gallons.

Now, if he doesn't paint the smaller room, which takes 2 coats paint, which is 3.2 gallons, he will have 4.8 gallons left (8 - 3.2).

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
