Identify Given Expression: Identify the given expression and the value to be substituted. $\newline$ The expression for the length of the paper stock is $2w + 4$ , where $w$ represents the width of the photo. We are given that the photo is $8.5$ inches wide.
Substitute Width: Substitute the given width of the photo into the expression. $\newline$ Substitute $w = 8.5$ inches into the expression $2w + 4$ to calculate the length of the paper stock. $\newline$ $2(8.5) + 4$
Perform Multiplication: Perform the multiplication part of the expression. $\newline$ Calculate $2$ times $8.5$ inches. $\newline$ $2 \times 8.5 = 17$ inches
Add to Find Total Length: Add the result of the multiplication to $4$ inches to find the total length of the paper stock. $\newline$ Add $17$ inches to $4$ inches. $\newline$ $17 + 4 = 21$ inches
