a. 
b. 
Answer:
55
Step-by-step explanation:
hope it helps you.....
We have that
[√(2x+1)]+3=0
for x=4
[√(2*4+1)]+3=0
[√(9)]+3=0
3+3=0----------6 is not zero
therefore
the solution is not correct for x=4
[√(2x+1)]+3=0--------> [√(2x+1)]=-3---------> <span>There is no real solution for that equation
</span>Because (2x+1) >= 0
the solution is with complex numbers
Answer:
x = -5
Step-by-step explanation:
x - 15 = -20
+ 15 + 15
x = -5
