What is the interest if a sum of $5200 is invested for 36month at 15% per annum

I = 2,340

Step-by-step explanation:

The formula for interest is

I = P × R × T / 100

P = $5200

R = 15%

T= 36 months; T is meant to be in years so we will convert it from months to years

1 year = 12 months

So 36 months

= 36 /12 = 3 years

I = (5200 × 15 × 3)/100

I = 234,000 / 100

I = 2,340

$2,340

Step-by-step explanation:

36 months = 3 years

15/100 × 5200 = 780 per annum

3 years: 780×3 = $2,340

step-by-step explanation:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
