The perimeter of the quadrilateral is 60 centimeters. Find the length of each side. x+6
x2-3x
x+8
3x-2
Side one = x+8 =
cm
Side two = x + 6 =
cm
Side three = x - 3x =
cm
Side four = 3x - 2 =
cm

ok then what happened.

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret

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

its line 2 i just added the rest or else it wouldn't let me answer
