pearl will put wire around a rectangular lot with a width of 20m and a length that is two times its width. how many mters of wire will she need?

Let's see what to do buddy...

_________________________________

STEP (1)

First we need to find the length.

(( length is two times the width ))

Length = 20 × 2 = 40 m

_________________________________

STEP (2)

Pearl will put wire around a rectangular.

Around of rectangular = Perimeter of it

So we must to find the perimeter of the rectangular.

So Pearl needs 120 meters of wire.

And we're done.

Thanks for watching buddy good luck.

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.
