Final answer:
To find the values of m and n when A = 32, we can substitute the value of A into the equation A² = mA + nA and solve for m and n. The values of m and n are m = 32 - n and n = 32 - m.
Step-by-step explanation:
To find the values of m and n, we are given that A = 32 and A² = mA + nA. We can substitute the value of A into the equation and solve for m and n. 
 
A² = mA + nA 
(32)² = m(32) + n(32) 
1024 = 32m + 32n 
 
We can divide both sides of the equation by 32 to isolate m and n. 
32m + 32n = 1024 
m + n = 32 
 
Therefore, the values of m and n that satisfy these equations are m = 32 - n and n = 32 - m. 
For example, if we let m = 5, then n = 32 - 5 = 27.
