Step-by-step explanation:
<u>Step 1: Define</u>
7s² + 9 + -2s²
<u>Step 2: Simplify</u>
- Rewrite: 7s² + 9 - 2s²
- Combine like terms (s²): 5s² + 9
The expanded form of that number is 2,000,000 + 300,000 + 5,000 + 10 + 2.
Answer of 9 = 7 because those red arcs mean that both of those angles are the same, so if the angle on the right is 7, the angle on the left is 7
Answer of 11 = 60, because this is a equilateral triangle, which means all the sides are the same.
180 - 60 = 120 (180 is in the equation because all interior sides of a triangle add up to 180)
120 divided by 2 = 60
The formula of a cylinder is 2πr (r+h)
2π4 (4+9)
8π (13)
25.13 (13)
326.73
Cubes: area = a^3
3x3x3 = 27
326.73 / 27 = 12.1
