Teresa is working on several ideas and she is also involved in the landscaping of the garden of the hotel.

PART 1: The garden

1. The garden of the hotel has a certain shape as seen in the figure below. Teresa wants to plant roses in that garden The diagram shows the shape and dimensions of Teresa’s rose garden.
a. Find the area of the garden.
b. Teresa wants to buy mulch for her garden. One bag of mulch covers 12 square feet. How many bags will she need?

where's the diagrams?

what is the original number? you forgot to add it.

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.

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
