In order to do this you can <span>factorise it to get
(x+1)^2 + (y-5)^2 = 16 = 4^2
hence centre is (-1,5) and radius is 4
</span>I hope this is what you are looking for
Answer:
20
Step-by-step explanation:
if x is 20
6x would be 120
3x would be 60
120 + 60 = 180 which checks out
180 is the degree amount of a straight line
Answer:
hypotenuse is not a rational number
Step-by-step explanation:
In a Right angled triangle , if a, b are the sides and h be the hypotenuse then relationship between them is given by
=
+ 
Here,
a= 4 in. [Given]
b = 6 in. [Given]
Thus ,
=
+ 
= 16 + 36
= 52.
h =
= 7.21110255......
Clearly, h is not a rational number
1. If y<span>ou have jogged 5 miles from the park at a rate of r miles per hour, then the time you need to do this is

hours (

, where S is distance, v-speed and t-time).
</span>
2. W<span>hen you run back to the park, your average speed increases by 1 mph and become r+1 mph.
</span>
3. I<span>t takes

hours to jog 5 miles back to the park</span>
4. T<span>he total jogging time T is

hours.</span>

5. If you jogged away from the park at an average speed of 4 miles per hour, then r+1=4 and r=3. The expression
