SOLUTION:
We are to calculate the shaded area of the given shape.
CONCEPT:
This is a triangle that a rectangle was cut out from.
To calculate the shaded area of the given shape, we are to find the area of the triangle and then subtract the area of the recangle that was cut out.
The shaded area = Area of the triangle - Area of the rectangle
Answer:
A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. For example, the absolute values of 4 and -4, or |4| and |-4|, are both 4.

Step-by-step explanation:
Answer:
It is a multiple of 8
Step-by-step explanation:
The product may or may not be a factor of 8. We usually think of the factors of an integer as being positive integers, so the factors of 8 would be 1, 2, 4, or 8. If 8n is to be a factor of 8, then n must be 1/8, 1/4, 1/2, or 1. This will not be the case in general.
__
The product of 8 and any number is a multiple of 8. (Again, we usually think of a multiple of 8 as being an integer, which would require the number n to be an integer.)
__
No product of two (integer) numbers is a prime number. If 8n is to be a prime, then the value of n must be <em>(some prime number)/8</em>. Again, this will not be the case in general.
__
n is a factor of the product; not the other way around.
