Rob won 60 lollipops playing the bean bag toss at the county fair. At school he
gave two to every student in his math
class. He only has 2 remaining. How
many students are in his class?

28

Step-by-step explanation:

If you have 60 lollipops, and you give two to each person, 60 divided by two is 30. Then, you subtract 2, because he has two remaining, and that gives an answer of 28.

hope this helped!

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,
