Does anyone know the answers to this? and please show work (I’ll mark you brainliest)

8) a.

9) c.

10) b.

11) b.

12) c.

Step-by-step explanation:

8.) 2x^2 + (4x-6x^2) + 9 - (6x+3)

Simplify: 4x^2 - 2x + 6

9.) -4x + 10 > 5x + 55

Subtract 10: -4x > 5x +45

Subtract 5x: -9x > 45

Divide by -9: x < -5

10.) 5(3 - x) < -2x + 6

Simplify: 15 - 5x < -2x + 6

Subtract 15: -5x < -2x - 9

Add 2x: -3x < -9

Divide by -3: x > 3

11.) -28x^2 + 35x

Divide by -7x: 4x - 5

-7x(4x - 5)

12.) 9q^2 - (3q - 7) + 5q^2

Simplify: 14q^2 - 2q +
