2w + 4\ncarly is cutting a piece of paper stock based on the width of a photo. the expression above describes the length of the paper stock, in inches, for a photo that is w inches wide. if the photo is 8.5 inches wide, what is the length of the paper stock in inches?
Answer
Explanation:
Step1: Identify the variable value
The width of the photo $w = 8.5$ inches. The length of the paper - stock is given by the expression $2w + 4$.
Step2: Substitute the value of $w$
Substitute $w = 8.5$ into the expression $2w+4$. We get $2\times8.5 + 4$. First, calculate $2\times8.5=17$. Then, $17 + 4=21$.
Answer:
21
