Dona found that she had 7 almonds left over after filling a number of bags with 25 almonds each. She let b represent the number of bags and wrote an expression to represent the total number of almonds. She found that b = 20 and then substituted to find the total number of almonds. Which statements should be part of Dona’s solution? Check all that apply.
Dona had 507 almonds.
To evaluate, substitute 25 for the variable.
Write the expression StartFraction 25 Over b EndFraction + 7.
Dona had 157 almonds.
Write the expression 25 b + 7.
Twenty-five times 20 equals 500.
The operations needed are multiplication and addition.

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.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
