Answer:

(2x - 1)( -  {x}^{2}  + 4x + 6) \\  = 2x \times  -  {x}^{2}  + 2x \times4x + 2x \times  6  \\  - 1 \times  -  {x}^{2}  - 1 \times 4x - 1 \times 6 \\  =  - 2 {x}^{3}  + 8 {x}^{2}  + 12x  +  {x}^{2}  - 4x - 6 \\  =  - 2 {x}^{3}  + 9 {x}^{2}  - 8x - 6 \\ thank \: you

I will mark you as brainliest if you're answer is correct​
GalinKa [24]

Answer:

perimeter = 28.13 cm

Step-by-step explanation:

Calculate the length of a line drawn from A to C.

sin 85 = b/8, b = 7.97

cos 85 = c/8, c = 0.697

AC² =7.97² + (6 + 0.697)² = 63.52 + 44.85 = 108.37

AC = 10.41

Now you have a right triangle ADC with a known hypotenuse and  one leg.

Using the Pythagorean theorem:

DC² = 10.41² - 5²

DC² = 108.37 - 25 = 83.37

DC = 9.13 cm

perimeter = 5 + 6 + 8 + 9.13 = 28.13 cm

Determine whether the underlined value is a parameter or a statistic.
hram777 [196]

Since the value is taken from a population, the value is a parameter.

<h3>Parameter and Statistic:</h3>

  • If the information is taken from a sample, it is called a statistic.
  • If the information is taken from a population, it is called a parameter.

For this problem, the students of the class are the population, as all students are considered for the calculator of the mean, hence the value is a parameter.
