The multiple zero is x = -4.
The multiplicity is 2 because there are two values of x.
The slope:
m = ( y2 - y1 ) / ( x2 - x1 ) = ( 8 2 ) / ( 3 - 2 ) = 6 / 1
m = 6 ( we have the same slope for AB and A`B` )
AB = √[( 3 - 2 )² + ( 8 - 2 )²] = √37
A`B` = 3.5 √37 = 21.29
7/3=2.3 but you can't have a desamal so it would be 2.
1km = 1000m is this what are you looking for
4x + 8.....the factor is 4
4(x + 2)
