Use what you know about factoring to explain how you can factor he expression 18x + 30y + 9z. then factor the expression

3(6x+10y+3z)

Step-by-step explanation:

Factoring is a mathematical representation of the expression with the help of common factors.

In this expression we have given terms and their coefficients. Since we cannot factorize the terms, they will be intact in the process.

We can factorize this expression with the help of prime numbers:

2 * 3 * 3 * x + 2 * 3 * 5 * y + 3 * 3 * z

And finally we will be able to obtain common factor from this expression:

3 ( 6x + 10y + 3z) - That's the final answer, we cannot factorize further.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
