Answer:
-4 or -3
Step-by-step explanation:
Calculate the determinant:
D = b^2 - 4ac = 49 - 48 = 1
Apply the formula:
x = (-b +- sqrt(D))/2a = (-7 +- 1)/2 = -4 or -3
Answer:
A = {CBA, CAB, BCA, ACB}
Step-by-step explanation:
9 = 25%

The number of meters= 15.8496 metres
The school need to add a further 1.8496 metres
