Answer:
2(n*3 + 7) = 80
Step-by-step explanation:
2(n*3 + 7) = 80
n*3 + 7 = 40
n*3 = 33
n = 11
You can split the hexagon into 6 triangles. To do so, connect opposite vertices.
Answer:
I believe (not confident) You take 180-28 and divide that by 2. (76 degrees)
We know that the top angle of the triangle is 28 degrees because vertical angles are congruent.
Step-by-step explanation:
Answer:
1. 4, 4, 6, 8
2. 5, 11, 3, 1
3. 11, 27, 111
4. 
5. 
Step-by-step explanation:
For the tables remember that after you solve any negative number will turn positive
For 4-5 just plug in what is in the parenthesis into x and solve
There are 25 identical squares arranged inside the 5 by 5 square matrix. From the drawing it's evident that the length of the side of any one of the smaller squares is just 1. Thus, the perimeter of this one smaller square is P = 4(1), or 4.
The desired perimeter is 4.
