A trapezoid with legs MN = FD is an isosceles trapezoid.
An isosceles trapezoid has diagonals that are congruent, therefore: MF = ND.
A quadrilateral with diagonals congruent and perpendicular is a square.
In a square, the height coincides with the side.
The area of a square is given by A = s²
Therefore, the area of MNFD is h²
Answer:
4056
Step-by-step explanation:
39 necklaces
104 beads/necklace
number of beads = number of necklaces * number of beads per necklace
number of beads = 39 * 104 = 4056
We know the yint, so lets find the slope. (0,-12) and (8,-2) -2--12/8-0 or 10/8 or 1.25
So, the slope is 1.25
The answer is y=1.25x-12
The perimeter would be 7+7+4+4 or 14+8 which equals 22 and the area would be 7x4 which is 28
On the problem you have given, the y ingercept shows the amount of time in hours it takes for the number of customers, so it would cross at 5 and represent 0 customers
