Evaluate A² for A = -3.
(-3)² = (-3) * (-3) = 9
Your answer is 9.
If the question is, however, evaluate A2, which is 2A, for A = -3, then the answer is:
2A = 2(-3) = -6.

Answer: yes they have a proportional relationship
Step-by-step explanation:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
Step one : let us test say c=1
F=9/5*1+32
F=9/5+32
F=1.8+32
F=33.8
Say c=2
F=9/5*2+32
F=9/10+32
F=0.9+32
F=32.9
Observe that as c increases
F reduces Hence they have a proportional relationship
