80% of the test = 32 questions
100% of the test = x questions
Cross multiply
80*x = 100 * 32 Combine the right

Answer:
P(x) = 2x² + 74x + 644
Step-by-step explanation:
The first number is x + 23.
The second number is:
2(x + 23) − 18
2x + 46 − 18
2x + 28
The product is:
P(x) = (x + 23) (2x + 28)
P(x) = 2x² + 28x + 46x + 644
P(x) = 2x² + 74x + 644
