PLEASE HELP ME ASAP I NEED HELP The smith family is designing new plans for an in ground pool. Mr. Smith draws a rectangular shape with a length that is 5 feet longer than the height. A.) write a polynomial expression in simplified form, that represents the area of the pool. Show and explain how you got the area of the pool. Mrs. smith wants to add 2 foot concrete walkway around the edge of the pool. B.) Write a polynomial expression , in simplified form, that represents the total area of the pool and walkway. Show and explain how you got the area of the pool and the walkway. Mr. smith is unhappy with the 2 foot concrete walkway around the edge of the pool. He decides to put a different width around the pool. The total area of the pool and the walkway is given by the polynomial W^2+17W+66, where W represents the width of the pool. C.) Determine the width of the new walkway. Show all your work. Explain why you did each step.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
