Solve this , find the length and width of the given rectangle

The answer to your question is: l = 13; w = 3

Step-by-step explanation:

Data

Area = 39 cm²

length = l = x + 8

width = w = x - 2

Formula

Area = length x width = l x w

Process

39 = (x + 8) (x - 2)

39 = x² + 6x - 16

x² + 6x - 16 - 39 = 0

x² + 6x - 55 = 0

(x + 11) (x -5) = 0

x1 = -11       x2 = 5       There are no lengths negatives so the right answer is

                                   5.

Length = 5 + 8 = 13 cm

Width = 5 - 2 = 3 cm

Area = (13)(3) = 39 cm²

final answer is : )

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.
