Hi read the comment below

50 ! pls ! 12.  building codes regulate the steepness of stairs. homes must have steps that are at least 13 inches wide for each 8 inches that they rise.

a. discuss how to find the slope of the stairs.
b. describe how changing the width or height affects the steepness of the stairs.

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.

What is the value of the product (3-2i)(3+2i)?
