The area is (BK) times (AK or CK).
If you have no numbers given, it's not possible to find the length of BK, or the actual number that represents the area.
Answer:
Step-by-step explanation:
Reducing 3 from numerator and denominator,
(trying to isolate/get x by itself in the equation)
5(x + 6) = 50 Distributive property [distribute 5 into (x + 6)]
5x + 30 = 50 Subtraction [subtract 30 on both sides of the equation]
5x = 20 Division [divide 5 on both sides]
x = 4
Subtraction then division, the 2nd option
The handshake problem!
Each of the five will play against 4 others, but since A vs B can be considered the same game as B vs A, so there are 5*4/2=10 matches.
