Answer:
When you say that two numbers are relatively prime, it means that both numbers do not have a common factor except 1. Stephen is incorrect because 38 and 40 are both multiples of 2.
Answer:
Slope = -9/2
Two points are (-2,9) and (2,-9)
Step-by-step explanation:
The two points the equation should go through are (-2,9) and (2,-9), (Dark Green and Light Blue).
The slope-intercept is calculated using the two points above;
-9 - 9 = -18
2 - (-2) = 4
Slope = -18/4 or -9/2
Hope this helps!
Answer: 
Step-by-step explanation:
1. By definition you have that the difference of squares is:

2. Given the polynomial:

You can identify that there are two terms whose signs are different and they are perfect squares.
3. Therefore, you have:

Ans.5) you can re-write 3 3/10 as 33/10
Now, you have to find two numbers whose sum would be 33/10.
Try to fix the denominator, and change numerator...like
it would be 13/10 + 20/10 or 15/10 + 18/10.Ok..
You can do your 6th ques. in same manner.
