Me with this question and also show me the step of how you do this

-x represents miles per gallon

-y represents cargo weight

-vehicle traveled an average of 5.3 miles per gallon(x1) with load of 22 tons (y1)

- vehicle traveled an average of 6.3 miles per gallon( x2) with load of 18 tons( y2)

so, equation now becomes

so, option a) is correct

42 inches then 10 1/2 deep

(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
