N art museum has a pentagon-shaped room. When drawn to scale on a coordinate grid, the corners of the room are points A(18,24) ; B(9,24) ; C(9,10) ; D(16,8) ; E(22,16), shown in feet. The walls are 9 feet high. The museum is going to paint four of the walls: , , , and . Assume one gallon of paint is enough to cover 488 square feet.

How many gallons of paint should the museum purchase? Enter your answer as a whole number.

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

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.

i believe the answer is c.
