_______
7 2
9 + 3=12 so add a 1 to 4 + 2 which= 6 + 1=7
And our answer is 72 .
If there are 8 shelves and each have same number of books then what is 72 divided by 8.
It= 9. to find out the answer even though we know we will use it's factors just to make sure our answer is correct.
9 x 1=9
9 x 2=18
9 x 3=27
And remember the 9 represents the books and the number 9 is is timesing by is the shelf number.
9 x 4=36
9 x 5=45
9 x 6=54
9 x 7=63
And our last shelf 9 x 8=72
So there we go each shelf has 9 books on it.

Part A: The area of the new dining room is 64 feet greater than the old dining room.
You need to know the formula of finding the area, which is length times width. First, you find the area of the old dining room (320 ft) and the new dining room (384 ft). Then, you subtract the areas (384-320) to get 64 feet.
Part B: The length and width of the new rug could be 12x10. The length of the original dining room was increased by 4 to create the new dining room. So, in this problem, you just add the length of the original rug (8 feet) by 4 to get 12.
Hope this helps.
