Answer:
x = - 5
Step-by-step explanation:
3x - 3 - 6x = 12
group like terms
3x - 6x - 3 = 12
add similar elements
- 3x - 3 = 12
add 3 to both sides
- 3x - 3 + 3 = 12 + 3
simplify
- 3x = 15
divide both sides by 3
- 3x / 5 = 15 / - 3
simplify
x = - 5
I assume the solid is a "regular hexagonal prism", by which it means that the cross section is a regular hexagon with all sides and angles equal.
Also, the exact apothem is 9.5262... but we will adopt the given value of 9.5.
First lateral surface area
A1=6*side length*height=6*11*20=1320 units
Then the end areas
A2=2 faces * 6 triangles/face * [base * height (apothem) /2]
=2*6*11*9.5/2
=627 units
Total area=1320+627=1947 units
(42/5)*(25/7)=1050/35 or 30
Point e lies on plane b true or false
