Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
The number of sides and number of angles is proportional, for it takes two sides to make an angle. So there are more sides.
Also a cube is not a polygon because a polygon is two dimensional and a cube is 3d.

Answer: $0.48
Revenues > costs
7.5x – 100 > 79.86 + 5.8x
7.5x - 5.8x > 79.86 + 100
1.7x > 179.86
x > 179.86 / 1.7
x > 105.8
Then, the minimum number of objects that need to be sold is 106 (the smallest integer greater than 105.8)
11x+55=0
11x=-55
11x/11=-55/11
x=-5
