The value of square root 86 is between 9 and 9.5
Lets just convert them into improper fractions.
1) 4 and 1/12 = 49/12.
1 and 3/4 = 7/4.
2) 7/4 = 21/12
3) 21/12 + 49/12 = 70/12
Back to mixed fractions!

Step-by-step explanation:
Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9
