Answer:
8370
Step-by-step explanation:
(31x15)108 = (465)108
= 50220/6
= 8370
Factors of 48 : 1,2,3,4,6,8,12,16,24,48....all of these numbers can be subbed in for X to arrive at a whole number....so there are 10 different ways
Answer:

Step-by-step explanation:
When we divide polynomials by polynomials with more than one term, we use long division or factorization to simplify.
This polynomial isn't easily divided after factorization so we will use long division. And we will use the remainder theorem to write any remainder.

We start long division by finding what multiplies with x+5 to get
. This is 6x.
So
. We have 6x left as a remainder from 36x.
We now divide x+5 into 6x+35. What multiplies with x+5 to get 6x+35? 6.
So we have 6x+6 as our answer so far and after we multiply 6(x+5)=6x+30 we will have a final remainder of 5.
We write our answer as
.
Answer:
To the nearest hundredth : 628.32 
To the nearest whole number : 628
Step-by-step explanation:
The formula for the area of a circle is : 
To work out the area you would first need to work out the radius. You can do this by dividing the diameter of 40 cm by 2, this gives you 20 cm. This is because the radius is half of the diameter.
Now that we have worked out the radius, the next step would be to work out the area. You can do this by multiplying pi by the radius of 20 squared, this gives you 1256.64.
The final step is to work out the area of this semi-circle. You can do this by dividing the area of 1256.64 by 2, this gives you 628.32
. This is because a semi-circle is half of a circle.
1) Divide 40 by 2.

2) Multiply pi by 20 squared.

3) Divide 1256.64 by 2.
