Answer 2

To simplify the given expressions:

3. (y - 4) * 2 + 10y

Let's apply the distributive property:

= 2(y - 4) + 10y

= 2y - 8 + 10y

= 12y - 8

Therefore, the simplified form of the expression (y - 4) * 2 + 10y is 12y - 8.

4. (2y + 5) * 4 - 11y

Again, we'll use the distributive property:

= 4(2y + 5) - 11y

= 8y + 20 - 11y

= -3y + 20

Hence, the simplified form of the expression (2y + 5) * 4 - 11y is -3y + 20.
