PSYCHO15rus [73]3 years ago
6 0

Answer:

O x = - 6 or x = 2

Step-by-step explanation:

x² + 4x - 4 - 8 = 0

x² + 4x - 12 = 0

x² + 6x - 2x - 12 = 0

x(x + 6)x - 2(x + 6) = 0

(x + 6) (x - 2) = 0

x + 6 = 0 or x - 2 = 0

x = - 6 or x = 2

Thus, x = - 6 or x = 2

What is the mean, median, mode, and range of 8, 35, 10, 12, 14?
Ivan

answer:

mean: 15.8

median: 12

mode: no mode

range: 27

step-by-step explanation:

  • first know how to find each of the above and what they are
  • mean = (avg) add all the numbers, then divide by the number of numbers
  • median = the middle number from increasing order
  • mode = the one that repeats the most
  • range = the difference between the largest and smallest number

8, 35, 10, 12, 14

<u>mean</u>

8 + 35 + 10 + 12 + 14 = 79

  • there are five numbers

79 / 5 = 15.8

<u>median</u>

  • put them from smallest to largest

8, 10, 12, 14, 35

  • 12 is the median OR the middle number

<u>mode</u>

  • no number repeat, so no mode

<u>range</u>

35 - 8 = 27
