sam earned $4,000 from his business. he gave 1/5 of it to his son and daughter in law as a gift. he invested 1/2 of the remaining amount. how much did he have left?
I think Ive got the answer, would you mind checking?
Reiny I think I have found out the rectangle problem. Could you check and see if Ive got it correct?
wat? hes helping perfectly fine. I actually m learning something.
A cylinder has surface area of 402 cm2. The height is three times greater than the radius. What is the height of the cylinder?
x^2-1 would it be this?
Sorry the width is x+5, I think I combine the like terms, is that right?
Given that the area of the rectangle is 2x^2 + 9x - 5 , determine the length of the rectangle.
