9x>27X>3

12x² + 15x + 8x + 10 = 12x² + 23x + 10

This problem is all about compound interest except this time the value is going down not up. To increase a value by 8% you would multiply it by 1.08 as 8% is 0.08 (1+0.08). To decrease a value however you...

First off, you would start by substituting in the numbers that you already know.
Therefore you get: 35 = u + (4 x 5)
Remembering BODMAS you would then look at the equation and solve the bracket...

One basic method used here, when you have an equation and you add, subtract, multiply or divide one side of the equation from the equal sign, you must add, subtract, multiply or divide by the same value o...
