Answer:
6y(y^2-3x)
Step-by-step explanation:
6y^3-18xy=6y(y^2-3x)
This question would be a lot better if you had actually included the exercises. When a question talks about other questions that you already did, you need to include those too. Otherwise we don't know what the question is talking about. Fortunately I was able to figure it out without seeing the exercises, but just for future reference, you should include that extra information.
When two addends(things you add together) are negative, adding them is a lot like adding positive numbers; you just have a negative sign on the sum. For example,
4 + 5 = 9
-4 + -5 = -9

Answer:
Please check explanations
Step-by-step explanation:
Firstly, we calculate the area of the floor
That is the product of the sides
= 300 * 540 = 162,000 cm^2
What is left is to calculate the area of a tile
Since the tile is also rectangular, the area of each tile will be;
60 * 30 = 1,800 cm^2
Since we have both areas, we can now get the number of tiles needed to cover the floor
We can get this by dividing the area of the floor by the area of a tile
This is;
162,000/1,800 = 90
This means that 90 tiles will cover the floor
The cost of a tile
is £4.25
The cost of 90 tiles will be ;
£4.25 * 90 = £382.5
from here, we can see that the £400 is more than £382.5
So we can conclude that she has enough to spend on tiles
