Answer 1

[AI-generated answer — Bot GPT 3.5]

To multiply (7y-z)(y+3z), you can use the distributive property or the FOIL method.

Using the distributive property, you can multiply each term in the first binomial by each term in the second binomial:

(7y - z)(y + 3z)
= 7y * y + 7y * 3z - z * y - z * 3z
= 7y² + 21yz - yz - 3z²

Combining like terms, you can simplify the expression to:

= 7y² + 20yz - 3z²
