If quadrilateral J K L M is congruent to quadrilateral C B D A, which pair of sides must be congruent

SInce we don't know the exact shape of the quadrilateral we only know that J=C, K=B, L=D, M=A.

Step-by-step explanation:

This is because the letter order helps to define which sides are congruent to each other! I hope this helps!

the answer is side JK is congruent to side CB

Step-by-step explanation:

10.4 inches

step-by-step explanation:

2x2x2.6

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,
