Answer: x
Step-by-step explanation:
The inverse undos any changes to x, reversing those changes will leave x. Ex: f(x)=x+2. The inverse (from replacing x with y and y with x and solving for y) is h(x)=x-2. Plugging x+2 into h(x) (composition of functions) results in x. 2 and -2 cancel out.
If x = width, and its length is twice its width...that means it is 2 times its width....so the length of the rectangle = 2x
Answer: you would do -16 - 5 = -21
