Q.1.1

4m - n + 8n - 9m \\ 4m - 9n - 9m \\  =  - 5m - 9n

Q 1.2

ab + ( {a}^{2}  - 2b)

this can't be simplified.

Q. 1.3

4d - d(2d + 2) \\ 3d \times 2d + 2  \\  = 6d + 2

Q.1.4

4(b - 2) + 6(b - 1) \\ 4b - 8 + 6b - 6 \\ =  10b - 2

Rudiy27

Max's deck also has 40 blue cards, and for every 5 blue cards in his deck there are 9 red cards. His blue cards can be divided exactly into 8 groups (8 times 5 is 40), so he should also be able to divide his red cards into exactly 8 groups of 9 cards each. So there are 72 red cards in his deck (8 times 9 is 72).

Joey has a pool in his backyard and he wants to build a fence around the entire area joeys backyard is 12 meters wide and 14 met
Paul [167]
One side of the back yard is usually the back side of the house. 
But we won't worry about that ... we'll just go ahead and fence all
four sides, like you seem to have said.

Any rectangle has two sides that are the length and two sides that are the width.
So the distance around the back yard is

           (14 + 14)  +  (12 + 12)  =   52 meters.

          (That's called the "perimeter" of the yard.)

If every meter of fence costs $9.00 , then  52 meters of fence will cost

                  (52) times ($9.00)  =   $468 .                  plus tax.
