It looks like the parabola are going down, so  the coefficient should be negative,
B or C,
then we see that the parabola has x -intercepts (1,0) and (5,0)
these roots should be written as multiples 
x=1, so x-1=0
and 
x=5, so x-5=0,
so (x-1)(x-5) and negative first coefficient -2 at the same time. 
We can see only in the

Varvara68 [4.7K]

Answer:

 22 \frac{6}{7} × \frac{11}{2}  = 125 .71

Step-by-step explanation:

22 \frac{6}{7} × \frac{11}{2}

   ={[ ( 22 × 7) + 6] ÷ 7 } × \frac{11}{2}

    = \frac{160}{7} × \frac{11}{2}

    = \frac{1760}{14}

     = \frac{880}{7}

   = 125 .71
