Answer:
Step-by-step explanation:Area of a circle is πr2
Diameter of the cover is 20feet
Radius= diameter/2
Radius= 20/2
Radius= 10 feet
Since 1feet = 0.3045m
Then 10feet =3.045m
Area= 3.142*3.045*3.045
Area= 29.133m2
Answer:
10 points, sorry if wrong

Answer:
1, 7
Step-by-step explanation:
There are no other factors of 7.
Answer:
1) 2x+1 = 2x-4
2) 6x+2=3(2x+1)
3) -4x -5=-2(2x)+2
Step-by-step explanation:
We need to give three examples of equations where there would be no solution.
First we will define equation with no solution.
<em>If solving an equation you get the result as 3=5 but 3 is not equal to 5, so the equation has no solution.</em>
Examples of equations where there would be no solution
1) 2x+1 = 2x-4
2x-2x=-4-1
0=-1 ( false)
So, the equation has no solution.
2) 6x+2=3(2x+1)
6x+2=6x+1
6x-6x=1-2
0=-2 (false)
So, the equation has no solution.
3) -4x -5=-2(2x)+2
-4x-5=-4x+2
-4x+4x=2+5
0=7 (false)
So, the equation has no solution.
