Represent each of her employee's explanations with an algebraic expression that describes how many new tiles must be added to
an nxn square to build the next design.

Wilma
I must add 3 tiles to each of the four sides of the white
square, which is 4*3 tiles. Then I must add 1 tile at each corner. So the number of additional tiles added to the Design 2 square floor design is 4*3 + 4. Write an expression to represent this.

Expression:

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
