A(1.3) (3,1) idk if it’s right but seems like the right answer
B. Accuracy is if it's right or not. Precision is how many decimal places it goes out to. So it is precise but not accurate.
I believe it is C. The quadratic function.
Perimeter = 4 x sides
48 = 4 (x + 3)
48 = 4x + 12
36 = 4x
x = 9
Check:
x + 3 = 9 + 3 = 12
12 x 4 = 48
