Suppose you want to put a frame around the painting shown at the right. The frame will be the same width around the entire painting. You have 276 in.2 of framing material. How wide should the frame be?

The frame should be 36 + 2b + 16 + 2b

Step-by-step explanation:

To solve this question, let assign 36 in x 16 in as the dimension of the painting.

276 in^2 is the area of the framing material to be used.

Let the width of the frame around the frame be "b", thus; the dimension of the frame is 36 + 2b + 16 + 2b

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
