vlada-n [284]

Answer:

-2x²(x + 1)(x - 4)

Step-by-step explanation:

Hello!

Factor:

  • -2x^4 + 6x^3 + 8x^2
  • -2x^2(x^2 - 3x - 4)        Take out GCF

Think: What numbers add up to -3 and multiply to -4?

Answer: -4 and 1

Continue:

  • -2x^2(x^2 - 3x - 4)
  • -2x^2(x^2 - 4x + x - 4)
  • -2x^2(x(x - 4) + 1(x - 4))       Factor by Grouping
  • -2x^2(x + 1)(x - 4)

The complete factored form is -2x²(x + 1)(x - 4)

What is the per capita cost of a ​$2.6 million recreation center in a city with 110945 ​people?
kvasek [131]

Answer: $23 per person

2,600,000/110,945 = 23.43035 (round to 5 decimal places)

The two significant digits of 23.43035 = 23

thus making it $23 per person.

Here is another example:

4,500,000/260,732= 17.25910

Two significant digits of 17.25910 = 17.25910 (without rounding). However, if it was 17.54210 it would be $18 per person. Hope those two examples help. If not let me know.
