Answer 3

A) To simplify 3(4m - 1), we can distribute the 3 to both terms inside the parentheses:

3 * 4m - 3 * 1

This simplifies to:

12m - 3

B) To simplify -5(2a + 4), we can distribute the -5 to both terms inside the parentheses:

-5 * 2a - 5 * 4

This simplifies to:

-10a - 20

C) To simplify -m(a + b), we can distribute the -m to both terms inside the parentheses:

-m * a - m * b

This simplifies to:

-ma - mb

D) To simplify c^2(3c^2 - 4c), we can distribute c^2 to both terms inside the parentheses:

c^2 * 3c^2 - c^2 * 4c

This simplifies to:

3c^4 - 4c^3

E) To simplify 2x(x^4 + 4), we can distribute the 2x to both terms inside the parentheses:

2x * x^4 + 2x * 4

This simplifies to:

2x^5 + 8x

F) To simplify -3y^2(y^3 - 2y^2 + y), we can distribute the -3y^2 to all the terms inside the parentheses:

-3y^2 * y^3 + 3y^2 * 2y^2 - 3y^2 * y

This simplifies to:

-3y^5 + 6y^4 - 3y^3

G) To simplify (3a^2b - 2ab + 5)(-3a^2), we can distribute -3a^2 to all the terms inside the parentheses:

-3a^2 * 3a^2b - 3a^2 * (-2ab) - 3a^2 * 5

This simplifies to:

-9a^4b + 6a^3b - 15a^2

H) To simplify 3a(b - 4), we can distribute the 3a to both terms inside the parentheses:

3a * b - 3a * 4

This simplifies to:

3ab - 12a

I) To simplify (6x + y) * x^2, we can distribute (6x + y) to x^2:

(6x + y) * x^2

This simplifies to:

6x * x^2 + y * x^2

This further simplifies to:

6x^3 + yx^2

These are the simplified forms of the given expressions.
