PLE| HELP ME ): Which of the following can be used to construct a triangle?

A) 10cm 13cm 24cm
B) 14cm 32m 28cm
C) 25cm 13cm 22cm
D) 5cm 8cm 20cm

the answer is simple, because you have to add up each side of the triangle and match those sides with your choices. btw its C

Step-by-step explanation:

C

Step-by-step explanation:

Use Pythagorean Theorem:

a^2 + b^2 = c^2

For a triangle to be a triangle a^2 +b^2 has to be larger than c^2

25^2 + 13^2 = 653

22^2 = 625  

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
