Help with 14, 15, and 16 please ?
lara31 [8.8K]
14. 36x^2 - 16
      4(9x^2 - 4) =
      4(3x + 2)(3x - 2) <==

15. 3x^2 + 10x - 8
      (3x - 2)(x + 4) <==

16. 5x^2 - 16x + 15 = 4x - 5
      5x^2 - 16x - 4x + 15 + 5 = 0
      5x^2 - 20x + 20 = 0
      5(x^2 - 4x + 4)
      5(x - 2)(x - 2)
      x - 2 = 0....x = 2

The mean height of the students in Marta's class is 60 in. There are 18 students in her class. Write and Solve and equation to f
Mashcka [7]

Solution: Let x be the height of a student in Marta's class.

The mean height of 18 students in Marta's class is 60 inches

We know that:

Mean = \frac{\sum x_{i}}{n}

60 = \frac{\sum x_{i}}{18}

60 \times 18 = \sum x_{i}

\sum x_{i} = 1080

Therefore, the total measure of all 18 student's heights is 1080 inches
