This is the concept of algebra, to get the difference of the expression given we proceed as follows;
(k^2-9k+20)-(k^2-9k+20)
collecting like terms we get:
(k^2-5k^2)+(-9k-9k)+(20-20)
=-4k^2-18k+0
=-4k^2-18k
The answer is (-4k^2-18k)
Answer:
10+10

The answer is -0.8 welcome
ABC ~ A’B’C’
So, AB=A’B’ , BC=B’C’ , AC = A’C’
Given, AB=15 and A’C’=4
So, AC = 4 , A’B’ = 15
