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

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
