Carolyn is planning a community garden she would like the length of the garden to be 4 feet more than its width. Carolyn wants to find out how much it would cost to buy fencing to put around the entire garden. What expression can she use to represent the perimeter of the garden?

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb

i think the answer would be c

step-by-step explanation:

because it just is

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
