Answer:
second option is the answer of your question
The price before tax is $15.52
40-15=25 students not on student council
25/40 = .625 decimal
multiply by 100 to get percent
62.5% of students are not on student council
Estimating:
15 rounds to 20 and 40 rounds to 50
40% are in student council and that leaves roughly 60% not in student council.
The answer to the question
Answer:
x = 9 ⇒ second answer
Step-by-step explanation:
∵ (a + 3)(-2a² + 15a + 6) =
-2a³ + 15a² + 6a - 6a² + 45a + 18 =
-2a³ + 9a² + 51a + 18
∵ (a + 3)(-2a² + 15a + 6) = -2a³ + xa² + 51a + 18
∴ -2a³ + 9a² + 51a + 18 = -2a³ + xa² + 51a + 18
∴ x = 9
