What should be added to x^3+4x^2+5, so that it is completely divisible by x^2+5? here ^=power or exponent guys solve this sum it is urgent 5 points on it

 5x + 15

Step-by-step explanation:

Divide (x² + 5) into (x³ + 4x² + 5) to see what is needed to make a remainder of zero.

Let k represent the unknown number.

            x  + 4                        

x² + 5 ) x³ + 4x² + 0x + 5+k

         - (x³          + 5x)

                   4x²  -  5x  +  5+k

               -  (4x²           +    20)

In order to have a remainder of zero, 4x² -5x + 5 + k must equal 4x² + 20

Solve for k:

4x² -5x + 5 + k = 4x² + 20

      -5x + 5 + k = 20              subtracted 4x² from both sides

                5 + k = 5x + 20      added 5x to both sides      

                     k  = 5x + 15        subtracted 5 from both sides    

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
