You are designing a box for a cell phone. It must have a length that is three times the width and be 2 inches tall. Find the width that would produce a surface area of 160 square inches.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
