Lesley ran 2 3/5 miles in 7/12 of an hour. How many miles can Lesley run in one hour? A.3 18/35
B.35/156
C. 22 2/7
D. 4 16/35

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

no this is a nonlinear negative

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

570, the answer is 570, hope it
