A sidewalk with exterior dimensions 5xy units by 3xy units surrounds a rectangular pool at the town park. The pool is 2xy units wide and xy units long. Write an expression to find the area of the sidewalk. Then find the area

Here! :]

Step-by-step explanation:

Area of sidewalk = Area of the cover area of sidewalk minus area of pool

Area of sidewalk = ((5xy)*(3xy)) - ((2xy)*(xy))

Continue to solve

- =

Area of sidewalk =

da freeck kinda math is this just drop out

step-by-step explanation:

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.
