((x+2)(x+2))-((x-5)(1))=A
x^2+4x+4-x+5=A
x^2+3x+9=A
The larger one is (-11 + 41)/2 = 15.
The smaller one is (-11 -41)/2 = -26.
_____
For two numbers a and b with sum s and difference d, you can write the equations

Then adding the equations and dividing that sum by 2, you get

You can subtract the second eqution from the first and get a similar result for the smaller number

These are the formulas we used above.
An infinite set of numbers have this characteristic. Some examples:
0, 12
1, 13
2, 14
2.5, 14.5
Pick any number, add 12 to it, and the numbers you started with and ended with are your pair of numbers.
Hope this helps!
Answer:
scale factor = 
Step-by-step explanation:
To determine the scale factor, calculate the ratio of corresponding sides in the 2 figures. Ratio is image to original.
Comparing the top horizontal segments in both, orange to black.
scale factor =
