Their are 6 equilateral triangles in a regular hexagon:
The area of one triangle = (x²√3)/4, then:
1st answer: The area of the hexagon base: is 6 TIMES the area of one equilateral triangle [or, needed for 2nd, question, TOT AREA:(6x²√3)/4] = (3x²√3)/2] unit²
2nd answer: :
Volume of pyramid: (base area)(height)/3
Volume of pyramid: (3x²√3).(3x)/3 (because height = 3x, given)
Then Volume of pyramid= 3x³√3 unit³.
3 is the answer for the second question
and 6 for the 1st
Answer:
1. 4/7 = 16/28
Check:
(4/7)(4/4) = 16/28 = 16/28
2. 40/15 = 8/3
Check:
(40/15)/(5/5) = 8/3
3. 15/6 = 5/2
Check:
(15/6)/(3/3) = 5/2
4. 8/11 = 56/77
Check:
(8/11)(7/7) = 56/77
5. 9/2 = 63/14
Check:
(9/2)(7/7) = 63/14

Answer:
Cheryl's posts + 7 posts =Kevin Posts
K-C=7 or C+7+K I use them because C is Cheryl and K is Kevin
Operation=subtraction or addition because it could be K-C=7 or C+7+K
Cheryl wrote K-7=C posts
Answer:
in the first box it is "addition property of equality" and in the second box it is "multiplication property of equality"
