It has to be this simple right? 18 holders thirty candles. but if only one candle fits in each holder then there is only 18 decorations possible
The answer is B) There are exactly 4 students with 6 textbooks
Distance Formula: 
Point 1: (9,0)
Point 2: (5,-8)
D = sqrt[ (5 - 9)^2 + (-8 - 0)^2 ]
D = sqrt[ (-4)^2 + (-8)^2 ]
D = sqrt[ 16 + 64]
D = sqrt(80)
Hope this helps!
