Well, we should start by listing the factors
1,2,3,4,6,8,9,12,16,24,36,72
You can put these in pairs if it will help you,
1*72 2*36 3*24 4*16 6*12 8*9
If you look, you can see that in only one pair the length is twice the width.
So your answer is
W=6
L=12
First you do -3bk+9bk and that equals 6bk then since there are no more like terms the experssion would be simplified into 6bk+2-6b
HOPE THAT HELPED!
Answer:
17.) 12
18.) 1/15
Step-by-step explanation:
2 ÷ 
This problem is asking how many 's can go into 2 blocks. If you divide one box into 6 parts, each tiny box will be of the whole. Divide the other box into 6 parts as well, and you will get 12 of these parts. Check your answer by multiplying 12 by . The answer is 
which is also equal to 2.
÷ 5
For this one, think of it as we have one big box divided into thirds. We want to divide each portion by 5. So you should have 5 tiny boxes in each which gives you a total of 15 boxes. But if we look at it as one big box divided into 15 parts, we know that each of those is 
. Check your answer by multiplying by 5 and you get 
which is equal to .
Let me know if you have any questions, and good luck!

Total cost for tiles and paints is $924.
Step-by-step explanation:
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Therefore, the area of walls and ceiling is 1410 square meters.
Given: Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. Therefore,
Therefore, the total painting cost is $564.
Tiles will be required for floor. Let us find the area of floor.
Given: 1m squared floor tiles costs $3. So,
Therefore, the total cost for tiles is $360.
Now let us find combined total cost of tiles and paint.
Therefore, the combined total cost of tiles and paint is $924.
