Question 5: When a number is squared and then added to itself, the result is 30. What is the number?
The equation can be written as x^2 + x = 30. This is a quadratic equation that can be solved using the quadratic formula or by factoring. Factoring gives (x + 6)(x - 5) = 0, so the solutions are x = -6 or x = 5. Since we're looking for the positive solution, the number is 5.
Question 6: When a person is dehydrated, which vital organ is most impacted?
The kidneys are responsible for filtering waste and excess fluids from the blood. When a person is dehydrated, the kidneys have to work harder to concentrate urine and conserve fluid in the body. Prolonged or severe dehydration can lead to kidney damage or failure.
