Who knows how to do this I TRULY NEED HELP !!

Theres also a part b

. B b = 6

Next part: : c also equals 6

Given the triangles are congruent, you can set up an equation to solve.

b +54 = 0b

Subtract b from both sides.

54 = 9b. Divide both sides by 9

6 = b

Step-by-step explanation:

(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
