Answer 2

polynomial only for garden or both garden and walkway?

Answer 3

just the garden

Answer 4

for example im gonna qwrite a polynomial for both garden and walkway but you figure out the polynomial for only garden
(10+2x)(9+2x)
90+20x+18x+4x^2
4x^2+38x+90

Answer 5

the area of the garden only is 9*10 ft2. To get a polynomial you need the area of garden + pathway as given by janu16

Answer 6

To find b plug x = 2 into the polynomial and work it out.

Answer 7

Thank you for the help.
