Answer:yes
Step-by-step explanation:
49π (153.938) is the area of the circle.
Formula is πr²
π(7)²
49π
8>w
w>/= -3
Meaning the inequality is 8>w>/= -3
The answer you are looking for is no solution.
To find this, you first distribute the -5 into the parenthesis (-4r - 6). -5 x -4r = 20r and -5 x -6 = 30.Next, distribute the 5 into the parenthesis (6 - r). 5 x 6 = 30 and 5 x r = 5r.
The equation says 20r + 30 = 5r + 30. Now you solve for r.Subtract 5r from both sides. This leaves the equation to say 15r + 30 = 30. Then subtract 30 from both sides, to get 15r = 0.
At this point, since there is a zero on the opposite side of the variable, you can assume it will be no solution, since multiplying or dividing 0 by anything, is 0. However, I'll finish the problem, to show that it is no solution.
Divide 15 from both sides, leaving r = 0, which is no solution.
I hope this helps!
