Can someone please answer my question please answer it correctly please show work please I need it

39. 32 - 4 = 28

28 ÷ 2 = 14

C. 14

40. D. 84%

I'm guessing 84% based on how the rectangles look on my phone. I would have to know the irl measurements to work the problem out.

41a. b = 86 ÷ (3 3/4 + 1 5/8)

41b. b = 86 ÷ (3 3/4 + 1 5/8)

b = 86 ÷ (3.75 + 1.625)

b = 86 ÷ 5.375

b = 16

16 batches.

42. First let's find the width of the rectangle. Because the width = 1/2 the length, two widths equals (3.2a + 0.18b). Now, the two lengths will be this equation doubled- (6.4a + 0.36b). Now we add both together.

So, (8.6a + 0.54b) = 2Length + 2width = perimeter.

Therefore, Sarah's expression and reasoning was incorrect.
