Answer:
One less zebra
Step-by-step explanation:
T        z        l 
0       200   220 
1         160    175       (subtract 40 from 200  and 45 from 220)
2        120    130
3         80      85
4         40  =  40      <===== lion has zebra lunch before the river is reached
Zdistance = 200 - 40s
Ldistance = 220 - 45 s            where  's' is seconds 
 
        
             
        
        
        
Step-by-step explanation:
Let the area of rectangle with given points are as follows : 
A(-3,3) 
B(3,2)
C(4,-1) = C( x1,y1)
D(-2,-3) = D( x2, y2)
Now, 
-  The distance of CD = root under 
 (x2-x)^2 +( y2 - y1)^2 
 = root under (-2-4)^2 + ( -3+1)^2
 = root under (-6)^2 + (-2)^2 
 = root under 36 + 4
 = root under 40 
 = 2root 10 
Therefore; the unit number if CD is 2 root 10.
 
        
             
        
        
        
Answer:
![\sqrt[7]{b^{15}}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bb%5E%7B15%7D%7D)
Step-by-step explanation:
=> ![b^2*\sqrt[7]{b}](https://tex.z-dn.net/?f=b%5E2%2A%5Csqrt%5B7%5D%7Bb%7D)
=> 
Where bases are same, powers are to be added.
=> 
=> 
=> 
=> ![\sqrt[7]{b^{15}}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bb%5E%7B15%7D%7D)
