The total area of the model is 110m^2. write an equation to find x. b. solve the equation by completing the square. A.) (x+2)(x+2)=110; x=1.32m B.) (x^2+2)(2x+2)=110x; x=5.93m C.) (x+2)(2x+2)=110; x=5.93m D.) (x+2)(2x+2)=110; x=3.53m

do you have the measurements?

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
