7√15 - 2√15 = answer 5√15
simple
6² = 36
7² = 49
8² = 64
√64
The correct answer is 8
Because
In triangle ORB
OR=(OB^2-RB^2)^1/2
OR=(17^2-15^2)^1/2
OR=(289-225)^1/2
OR=(64)^1/2
OR=8
RB=AB/2 so I kept its value 15 and ^1/2 refers to square root
Answer:
the forth top price is $93
Step-by-step explanation:
(30 + 15 + 18 + x)/4 = 39
63 + x/4 = 39

63 + x= 156
63 + x - 63 = 156 - 63
x = 93
