Simplify A rectangle has a length of 2(x + y) and a width of 3(x − y). Write an
expression for the perimeter of that rectangle. Simplify the expression.

Hint To find the perimeter of a rectangle, you need to add up all the sides of the rectangle

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
