40.2
Step-by-step explanation:
Diameter = 16, Radius = 16/2 = 8
Central angle = 2π/5 radians = 72°
Sector area,
8²π×(72/360)

Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26

Step-by-step explanation:
First, you need to draw this out. Roughly, it should look a little something like the link i included in this answer. then u just draw a line tracing the points to make a rectangle (sandbox) and decide that the perimeter, or the distance around, would be 3+4+3+4 = 14 feet.
It might be d because the side are all the exact same size!
