The route that a trolley takes around a city can be represented by the functions x2 + y2 = 10. A train track's path can be described by the function x + y = 4. At which location(s) will the trolley and train meet?

A) (–1, 3) and (–3, –1)
B) (3, 1) and (–3, –1)
C) (1, 3) and (3, 1)
D) (–3, 1) and (1, 3)

(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

which expression can be used to convert 80 us dollars (usd) to australian dollars (aud)?

1 usd = 1.0343 aud

1 aud = 0.9668 usd

step-by-step explanation:
