Answer: -8.66666666667
Step-by-step explanation: Do it step by step. So 19+7= 26
Then 2-5= 3
So 26 divided by -3 = -8.66666666667
Answer:
c-c+a+|a|
5-5+4+|4|
8
Step-by-step explanation:
With some simple rearrangement, we can rewrite the numerator as
Then factorizing the difference of squares, 
, we end up with
For the scale factor, use the dimensions from similar sides:
Using 18 from the original image you would use 6 from the scaled image.
18 /6 = 3
This means the scaled image is 3 times smaller than the original. Because the scaled image is smaller divide 1 by the scale factor to get 1/3.
Q2:
The scale factor is 1 inch = 12 miles.
Multiply the total inches by 12:
6.5 x 12 = 78 miles.
Answer:
Porpotional
Step-by-step explanation:
because it is non proportional
