Answer:

A=8

B=6

C=14

Step-by-step explanation:

A+b+c=28

c+b=20

Substitute c+b for 20

A+20=28

A=28-20

A=8

c+a=22

Substitute a with 8

c+8=22

c=22-8

c=14

To get b, we substitute a with 8 and b with 14

A+b+c=28

8+b+14=28

22+b=28

b=28-22

b=6

Divide p(x)=x^4+6x^3+7x^2-6x-8 by x+4. What is the remainder

postnew [5]

Use the remainder theorem; dividing a polynomial $p(x)$ by $x-c$ leaves a remainder equal to $p(c)$ . Here

$p(x)=x^4+6x^3+7x^2-6x-8$

$\implies p(c)=(-4)^4+6(-4)^3+7(-4)^2-6(-4)-8=\boxed{0}$
