A taxi travels 25 kilometers east of an airport .Then ,it travels from that point to a point that is 40 kilometers west of the airport. Finally , the taxi returns to the airport. How far did the taxi travel

130 km

Step-by-step explanation:

First he goes 25 km east of airport so D1 = 25 km

He them returns and goes 40 km west of airport i-e first he will come back to airport travelling 25 km back and then he will go west of airport 4o km - so total distance = D2 = 25+40= 65 km

He then returns back  again and travels 40 km back, so distance back from west =D3=40 km

So, total distance he traveled = D1=D2+D3 =25+65+40=130 km

i have no idea

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
