Hey there,

Your question states: <span>Part A-Find the PERIMETER of the outside edges of the frame.

You will do 5+5+7+7 and you will get 24.

Your correct answer would be 24 ft
_____________________________________________________________

Your question states: </span><span>Find the AREA of the inside of the frame where the picture would belong and the area of the entire frame using the outside values. So I will basically do everything I did for (Part A) but I will do 25 x 35 and this would give me 875.

The area of the frame above would be 875 ft.
_____________________________________________________________

Your question states: </span><span>If the area of the frame was 64 inches², what would be 2 possible sets of dimensions that could be used to make a frame with that area?

You would do 64/4 because this is a square and a square has 4 sides. So I will do 64/4 and I will get 16.

16 will be your correct answer.
_____________________________________________________________

Your question states: </span><span>The frame is being enlarged to hang on a gallery wall. Using the scale factor of 1in=2.5ft., give the new dimensions of the outside edges of the frame.

</span>So if each each equals 2.5. I will do 2.5 x 5 and that will give me 12.5. I will also do the same on the other side because this is a square.So that means I will do 12.5+12.5 and I will get 25. Now for the number 7, I will do 7 x 2.5 and that will give me 17.5 but sense its a square I will do the same on the other side and I will get 35. So then I will add 25+35 and I will get 60.

The perimeter of the frame would be 60 ft.
_____________________________________________________________

Hope this helps your brain.

Do the graphs of the two equations parallel lines Y=4x - x and 2y = 4x + 5
tamaranim1 [39]
Parallel lines have the same slope so you first have to identify the slope of the lines.
The first lines has a slope of 4 and the second line has a slope of 2.
This means the lines are NOT parallel
