Based on the answers you've provided for the Quick Check on solution sets of quadratic equations for 9th grade Algebra 1A, here’s a summary that includes the answers and brief explanations where applicable:

Both x = -1 and x = 7/3 are solutions.
- This implies that the quadratic equation has two specific roots, indicating it may have been factored or solved using the quadratic formula.
24 feet
- This likely refers to the maximum height or distance in a quadratic context. Without the specific problem, we assume it relates to a real-world scenario involving quadratic equations.
C) Yes, x = -3 is a solution.
- This is validated by substituting x = -3 back into a quadratic equation and confirming that it satisfies the equation, as shown in the evaluation.
A) two
- This likely refers to the number of solutions or roots a quadratic equation can have, which may vary based on the discriminant (greater than, equal to, or less than zero).
C) two
- This also suggests a confirmation of the number of solutions from another perspective, repeating the conclusion that a quadratic can generally have two real solutions.
