HELP I WILL MARK AS BRAINLIEST Which property of parallelograms justifies that GDE = EFG?

Opposite sides of a parallelogram are equal.
Opposite sides of a parallelogram are parallel.
Adjacent angles of a parallelogram are supplementary.
Opposite angles of a parallelogram are equal.

Opposite angles of a parallelogram are equal.

Step-by-step explanation:

The properties of a parallelogram are:

=> Opposite angles of a parallelogram are equal.

=> Opposite sides of a parallelogram are equal and parallel.

=> Adjacent angles of a parallelogram are supplementary.

So, the property that describes that ∠GDE = ∠EFG is that "opposite angles of a parallelogram are equal." because the angles are opposite to eachother and so, equal!

Hope this helped!

answer: -0.5 would be the most likley outcome

step-by-step explanation:

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,
