Use point-slope form to write the equation of a line that passes through the point (12,3) with slope

y-3=(4/3)(x-12)

Step-by-step explanation:

1. Remember y-y1=m(x-x1)

2. y1 is the y coordinate of a point on the line

3. m is the slope of the line

4. x1 is the x coordinate of a point on the line.

5. Insert variables into equation

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

(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
