Answer:
it should be 6 not 100% sure though
Step-by-step explanation:
(-6y-2)+5(3+2.5y) expend
-6y-2+15+12.5
6.5y+13
218, 314 are the two values do the middle 95% of the lengths of all pregnancies fall.
The surface area of the regular hexagonal pyramid is
SA = (1/2) pl + B
where p is the perimeter of the base, l is the slant height of the pyramid, and B is the area of the base
The area of a regular hexagon is 3 sh
where s is the length of the side and h is the length of the apothem.
So,
SA = (1/2)(6)(12) (11) + 3(12)(6sqrt3)
SA = 770 square meters
