<u>Area of the frame with picture:</u>
- A = lw
- A₁ = (x + 4)(x + 7) = x² + 11x + 28
<u>Area of the picture:</u>
<u>Area of the wooden frame is the difference of the above values:</u>
- A₃ = A₁ - A₂
- A₃ = x² + 11x + 28 - x² - 3x
- = 8x + 28
b)
<u>When x = 5, the picture frame area is:</u>
- A₃ = 8*5 + 28 = 40 + 28 = 68 in²
Bobby would have bought 1.21 dollars worth of items from the school store. This because you would line up the problem. In mine, I did 21 on top, 45 in the middle, and 55 on the bottom. And then I added the 1 + 5 + 5 in the right column which equaled 11. This required me to carry the one to the other side and put the other one down in the answer. Then I did 2 + 4 + 5 + 1 = 12. Then you have to add a decimal which makes the most sense to put it in between the 1 and 2. I hope that this is a help and have a great day! If you can please mark this brainliest and contact me if you need more help!
