Step-by-step explanation:
A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0
B) Since the discriminant is 0, this means the equation only has one root.
C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)
Answer:

= 10N + 30
Hence, the answer is A.
Hello there!
2x - 7 = 3
Solve for x
2x = 3 + 7
2x = 10
x = 10/2
x = 5
Therefore, the number of x in the equation is 5
