I believe the mean its 14!
1. Check the picture attached. Consider the half of the 8-sided die, that is the pyramid ABCDE:
2. The perimeter of the base is 6, so each side of the base is 6/4=3/2
3. The distance between the tallest points is 2 cm, si the height of Pyramid ABCDE is 1 cm.
4. Consider the right triangle EOM in the figure:
EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is

(cm)
5. So side EBC has area

6. The total area is 8*Area(EBC)=
Answer: 4( x - 5)( x - 2)
Step-by-step explanation:
4x^2 -28x + 40
4 ( x - 5)(x - 2)
Answer:
3/11 x 4/9 = 4/33 or in decimal form = 0.121212
Step-by-step explanation:
Answer:
C: 12x + 40
Step-by-step explanation:
We are told that the Cost to rent tables from Company A is;
f(x) = 4x + 25
Also, we are told that the Cost to rent tables from Company B is;
g(x) = 2(4x) + 15
Thus, total cost for Lorenzo to rent x number of tables and the chairs he needs is;
Total = f(x) + g(x)
Total = 4x + 25 + 2(4x) + 15
Total = 4x + 25 + 8x + 15
Total = 12x + 40
