1. The given graph is octagon:
a is the side of the side:
Area of octagon = 2(1+√2) a²= 2(1+√2)(4)²= 77.25 unit²
2. it is similar to Pentagon:
Let A area, l length, w width, b base and h height:
A= lw+1/2b₁h₁+b₂h₂
A= 7(2)+1/2+7*3 =35.5
0.8 is the correct answer
Hope this helps. Math isn’t my best but I just did this in my math class
Answer:
N=9/2
Step-by-step explanation:
Question: <u>10=2N+1</u>
1) Subtract 1 from both sides:
9=2N
2) Divide both sides of the equation by 2:
N=9/2
(66•6)-9
You are still multiplying 66 and 6 and subtracting 9 after which is now using the distributive property.
