Answer:
Ben is incorrect
The solutions are x>-3 and x < 3
Step-by-step explanation:
we have
Multiply by -1 both sides
Adds 9 both sides
The solutions are
and
-----> Multiply by -1 both sides ----> 
therefore
The solution is the interval (-3,3)

Answer:
+- 5 and +- 3
Step-by-step explanation:
qn 2:
4r² = 91 + 9
4r² = 100
r² = 25
r = +- 5
qn 3:
4r² = 29 + 7
4r² = 36
r² = 9
r = +- 3
(x-3)2+(y-4)2=24
2x-6+2y=24
2x-14+2y=24
2x=24+14-2y
2x=38-2y
x=19-y
