Step-by-step explanation:
<u>Step 1: Identify</u>
We have an irregular hexagon. We have n = 6 sides.
<u>Step 2: Find Angle Sum</u>
- Substitute in <em>n </em>[SA]: 180(6 - 2)°
- (Parenthesis) Subtract: 180(4)°
- Multiply: 720°
Answer:
C
Step-by-step explanation:
We need to use the distributive property to expand this.
The property is:
a(b+c) = ab + ac
So, the part " -3(2b+1) " will becomes:
-3(2b+1) = (-3)(2b) + (-3)(1) = -6b - 3
So, the problem becomes:
-2b -3(2b+1) = -2b -6b -3
Now, we add like terms:
-2b - 6b - 3
(-2-6)b - 3
-8b - 3
This is the correct answer, answer choice C
