Answer:
4,5,6 / 6,8,10 / 5,12,13 / ....
Step-by-step explanation:
Base on the pythagorean theorem, we have : a² + b² = c².
The first set : 4,5,6 - 4² + 5² = 6² (a possible set)
The second set : 6² + 8² = 10² (another possible set)
The last set : 5² + 12² = 13² (also possible)
There are a lot more sets, but I'll only list 3. Hope this helps :)
First solve the 2 inequalities for x:-
x > 0 or x <= -5
The last choice is the correct one.
There would be four sides, three around and the bottom base <span />
Solving
S = 3F - 24
for F gives
S + 24 = 3F
(S + 24)/3 = F
The best choice is the last one:
F = (S + 24)/3
