Which shows one way to determine the factors of x3 – 9x2 + 5x – 45 by grouping?x2(x – 9) – 5(x – 9)
x2(x + 9) – 5(x + 9)
x(x2 + 5) – 9(x2 + 5)
x(x2 – 5) – 9(x2 – 5)

Answers

Answer 1
Answer: x³ - 9x² + 5x - 45

x²(x - 9) - 5(x - 9) ⇒ x³ - 9x² - 5x + 45 INCORRECT
x²(x + 9) - 5(x + 9) ⇒ x³ + 9x² - 5x - 45 INCORRECT

x(x² + 5) - 9(x² + 5) ⇒ x³ + 5x - 9x² - 45 CORRECT
It just needs to be rearranged.

x(x² - 5) - 9(x² - 5) ⇒ x³ - 5x - 9x² + 45 INCORRECT
Answer 2
Answer:

The answer choice which shows a way to determine the factors by grouping is; x(x² + 5)–9(x² + 5).

How do you round 328 to the nearest ten

Answers

328 rounded to the nearest ten so where would your tens place be
328
the 2 is in the tens place now how to round to the nerest tens place look to the right of the tens place
4 and lower numbers go DOWN
5 and higher numbers go UP
so the 8 is in the higher numbers so you would bring 328 up to 330
so 328 rounded to the nearest ten would be 330

The ratio of chaperones to students on a field trip is 2:7. There are 14 chaperones on the field trip. In all, how many chaperones and students are on the field trip

Answers

To find the total number of chaperones and students on the field trip, you can use the given ratio and the fact that there are 14 chaperones. The ratio of chaperones to students is 2:7.

Let C represent the number of chaperones and S represent the number of students. According to the ratio:

2:7 = 14:C

To solve for C, you can set up a proportion:

2/7 = 14/C

Now, cross-multiply:

2C = 7 * 14

2C = 98

Now, divide both sides by 2 to find the number of chaperones (C):

C = 98 / 2

C = 49

So, there are 49 chaperones and 7 times as many students:

Students (S) = 7 * Chaperones (C) = 7 * 49 = 343

In total, there are 49 chaperones and 343 students on the field trip.
