Answer:

-2x² + 90x + 500

Step-by-step explanation:

Use FOIL method

Area of rectangle = length * width

                             = (50 - x)(2x + 10)

                             = 50*(2x) + 50*10 + (-x)*2x + (-x)*10

                             = 100x + 500 - 2x² - 10x

                             = -2x² + 10<u>0x - 10x </u>+ 500  {Combine like terms}

                            = -2x² + 90x + 500

What is the inverse of <br><br> X^2-2x+3
schepotkina [342]
So you have x, then you square it to get x^2, then you minus 2x, then +3
The inverse is going backwards so you -3 then +2x then square root x
So you get square root x + 2x -3
I'm pretty sure this is right, sorry if I'm wrong.
