The length of a rectangle is 8 inches greater than the width. the perimeter is 80 inches. what is the width of the rectangle?

lily decided to let w stand for the width of the rectangle. which problem-solving step was this?

a. check your answer and present the solution.
b. come to an answer.
c. understand the problem.
d. gather your resources.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
