Felixstowe a round face on the scale drawing below if the height of the lakes route 6 inches from the ground how long is the park that is on the ground

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

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.

the answer is

a.

x = 42

y = 10

i got it down chief.
