it's just the whole area minus the shaded area, right?
since the area of a rectangle is length * width, that gives you
(x+10)(2x+5) - (x+1)(x+1) = x^2 + 23x + 49
Now it's up to you to follow the set of instructions. Post your work if you get stuck.
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
A rectangle is shown with length x plus 10 and width 2 x plus 5. The inside of the rectangle is shaded other than an unshaded square with length x plus 1 and width x plus 1.
Write an expression for the area of the shaded region in its simplest form. Show all of your steps.

oobleck you want other people to have a hard time because you are?
what happened here? Lmao
Actually I think @ooblek was help because they helped me get my equation started so ty
First, combine the length (x+10) and width (2x+5) of the rectangle to get 2x^2 + 25x+50. Find the area of the white square (x+1)(x+1) to get x^2 + 2x+1. Then subtract x^2+2x+1 from 2x^2+25x+50 to get x^2+23x+49. This is what I got and I'm 95% sure it's right. I'd put it in more precise wording but that's the basic work. Please try your hardest in math, it's so important.
can people just stop man
I'm sorry, I'm not sure what you mean. Is there anything else you need help with?
