Answer:
+- 5 and +- 3
Step-by-step explanation:
qn 2:
4r² = 91 + 9
4r² = 100
r² = 25
r = +- 5
qn 3:
4r² = 29 + 7

r = +- 3
Answer:
D: no solution
...because none of the answers work for both of the equations when you plug in the x and y values
Sqrt[x] = -x
x= x ^ 2
x - x^2 = 0
-x(x-1)=0
x(x-1)=0
x = 1 or x = 0
sqrt 1 isn not equal to 0
x= 0
Step-by-step explanation:
I think that is the right answer I hope ut helps
