Answer:4x+15

Step-by-step explanation: PEMDAS. First you multiply 12x3 and 9x2 so you get 36-18. Then you subtract 18 from 36 leaving you with 18. Then you combine 18 and -3, leaving you with 4x-15.

12x^{3}  -  {9x}^{2}  + 4x - 3 =  \\  = 3 {x}^{2} (4x - 3) + 1(4x - 3) =  \\  = (4x - 3)( {3x}^{2}  + 1)

G<br> Express as a percent.<br> 4/5%
Aloiza [94]

Answer:

80%

Step-by-step explanation:

I'm assuming you meant express 4/5 as a percent and not 4/5%. So simply evaluate 4/5 to get 0.80. Now multiply this value by 100 to get the percentage which gives you 80%
