Step-by-step explanation:

Angle 2 and Angle 3 are vertical

2 = 3

Angle 2 and 6 are corresponding

2  = 6

Angle 2 and 7 are alternate exterior

2 = 7

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

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.
