Pls help helpp i am confused

3

Step-by-step explanation:4x^3x^2+12x+6 divided by (2x+1) gives a quotient of (2x^2-6x+9) and a remainder of -3. So you need to add 3 to the dividend to make it 4x^3-10x^2+12x+9.

you have to add 3

Step-by-step explanation:

you have to divide the polynomials and we find the remainder that keeps it from being perfectly divided is -3 so if u add 3 to the original polynomial it allows it to be perfectly divided

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
