0.25 is a rational number

Rational numbers are numbers that you can guess the number that is right after it or know the patterns like:

1.33333333333, 1.23456789, 1.25, 1.50, 1.0110111011110, ect

Irrational Numbers are numbers you cannot guess the number like:

1.844768461648917902179701, or π that has a infinite amount of numbers

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

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,
