85 point plz answer

1. combine the like terms to simplify the expression.
9x2 + 8y2 + 4y2 – 3x

a. 6x + 12y2

b. 9x2 + 12y4 – 3x

c. 6x + 12y4

d. 9x2 + 12y2 – 3x

2. use the distributive property and simplify the expression.

4+2(3x−1)+9

a. 3x + 14

b. 6x + 15

c. 6x + 11

d. 5x + 14

Step-by-step explanation:

1. Combine the like terms

9x2 + 8y2 + 4y2 – 3x

= 9x2 + (8y2 + 4y2) – 3x

= 9x2 + 12y2 – 3x

The answer is d.

2. Use the Distributive Property

4+2(3x−1)+9

= 4+2*3x−2*1+9

= 4+6x-2+9

= 6x+4-2+9

= 6x + 11

The answer id c.

1. Combine the like terms to simplify the expression.

9x2 + 8y2 + 4y2 – 3x

d.9x²+12y²-3x

2. Use the Distributive Property and simplify the expression.

4+2(3x−1)+9

4+6x-2+9

=c.6x-11
