Answer:
see explanation
Step-by-step explanation:
Given
(x - 2)² + 9 = 0 ( subtract 9 from both sides )
(x - 2)² = - 9 ( take the square root of both sides )
x - 2 = ±
yields no real solutions
There is no real number when multiplied by itself gives - 9
In fact the solutions to are said to be imaginary, that is ± 3i
where i =

Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) = 9.5
3x+4 = 9.5(2)
3x = 19-4
x = 15/3
x = 5
b) = 5
7+2x = 5(3)
2x = 15-7
x = 8/2
x=4
