Answer:

a) $2.75 b) $13.75

Step-by-step explanation:

since 8.25 is the total cost of 3 books, inorder to find the cost of 1 book, divide 8.25/3

that equals = $2.75  

then we need to find the cost of 5 books, so multiply the cost of 1 book by 5

so 2.75*5 = $13.75

Digiron [165]

Answer: 3x²-3y²+8xy

Step-by-step explanation:

When you multiply two factors, you want to use the FOIL method.

First

Outer

Inner

Last

(x+3y)(3x-y)                  [distribute by FOIL]

3x²-xy+9xy-3y²            [combine like terms]

3x²+8xy-3y²                 [rewrite]

3x²-3y²+8xy

Now, we know the product is 3x²-3y²+8xy.
