Answer:

The correct answer is: Option D) 5

Step-by-step explanation:

Given equation is:

3(x + 2) + x = 2x + 16

In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.

Putting x = 2

3(2 + 2) + 2 = 2(2) + 16\\3(4)+2 = 4+16\\12+2 = 20\\14 \neq 20

Putting x = 3

3(3 + 2) + 3 = 2(3) + 16\\3(5)+3 = 6+16\\17+3 = 22\\20 \neq 22

Putting x=4

3(4+2)+4 = 2(4)+16\\3(6)+4 = 8+16\\18+4 = 24\\22 \neq 24

Putting x = 5

3(5+2)+5 = 2(5)+16\\3(7)+5 = 10+16\\21+5 = 26\\26 = 26

The equation is true for x = 5

Hence,

The correct answer is: Option D) 5

For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-

df=n-1

Given : Sample size : n-1

Then, the number of degrees of freedom the t-value will have :-

df=15-1=14

Hence, the t-value will have 14 degrees of freedom.

Triss [41]

Answer:

Each one of the sides is equal to 7d-5

Step-by-step explanation:

A regular pentagon has 5 sides of equal length.

The perimeter of a regular pentagon is given by

P = 5s where s is the side length

35d -25 = 5s

Divide each side by 5

(35d-25)/5 = 5s/5

7d-5 =s

Each one of the sides is equal to 7d-5
