Answer:
20, 11
Step-by-step explanation:
x=first Number
x-9=second number
above two added together=31 or
x+(x-9)=31
2x=40
x=20 first number
x-9=second number
20-9=11 second number
20 (first number) + 11 (second number)=31
31=31
So these are set up into groups. you have 4 groups. you want to find 1/4 of the group and that would be 3 squares because 4 times 3 = 12
X(x+4)
(x+2)^2-4
(x+4)x
Hope this helps.
