Step-by-step explanation:
12f+10<75
12f<75-10 *carry the 10 over
12f<65 *simplify
f<65/12 *carry the 12 over
f<5.42 *simplify
This would be 3990 if you require a whole number but for a decimal it would be 3989.24

The two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.
<h3>What are the solutions to the quadratic equation?</h3>
Given the equation; 9x² + 4 = 0
First, we subtract 4 from both sides.
9x² + 4 = 0
9x² = -4
x² = -4/9
Take the square roots of both sides
x = ±√(-4/9)
Rewrite -4/9 as (2i/3)²
x = ±√(2i/3)²
x = ±(2i/3)
Hence,
x = 2i/3, -2i/3
Therefore the two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.
