Answer:
xy*(2x^2 + 7x^2 - y^2)
Step-by-step explanation:
You can get xy out of the expression since all have xy
That depends. If it is a fraction, can you cancel out some numbers? If it is an expression, can you combine like terms? Or do you need to factor?
Simple interest uses the equation/formula A=P( 1 + RT) where A = the amount after T years, T = the number of years, R = the interest rate, and P = Principal amount of what you started with. "65 hundred" = 6500
Just plug in to get 6500 = 5000(1 + 15R). Distribute to get 6500 = 5000 + 75000R. Subtract 5000 both sides then divide by 75000 to isolate the R.
You get 1500/75000 = R. R = 0.02 or 2%
The interest rate is 2%
