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
You would use the function root(Xsub2-Xsub1)^2+(Ysub2-Ysub1)^2.
Now plug in your numbers.
This gives you root(7-1)^2+(5-(-3))^2.
Simplify to root(6)^2+(8)^2. Simplify again to root36+64.
Simplify one more time to root 100. now solve.
Your answer is 10.

Answer: Choice C) $1,444.50</h3>
========================================================
There are two methods to get the answer.
The slightly longer method is to take 7% of the original price to get
7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50
The sales tax is $94.50
Add this onto the original price to get 1,350+94.50 = 1,444.50
----------------------------
A shortcut is to multiply the original price by 1.07
The multiplier 1.07 represents a 7% increase since
- 1 = 100%
- 0.07 = 7%
- 1.07 = 1 + 0.7 = 100% + 7%
So we will have 1.07*1350 = 1,444.50
I think that it’s A, Perpendicular (correct me if I’m wrong)
