Dorothy has a basket of apples. She weighs them and makes a table to show how many apples she has of each weight. weight (lbs) Number of apples
1/4 x 3
3/8 x 6
1/2 x 5
5/8 x 4
3/4 x 2

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

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,

mrb
