We need to write a proportion.
6/2 = (x+2)/x
3 = x² +2x
x² + 2x - 3 =0
(x + 3)(x - 1) = 0
x= -3, x= 1
Because we need to find length x, a length cannot be negative.
So, x = 1.
Answer:
120
Step-by-step explanation:
The polygon shown is a parallelogram with a base length of 15 and a height of 8
The area of a parallelogram can easily be calculated by multiplying the height by the base length
So A = 15 * 8
15 * 8 = 120
Hence, the area of the polygon is 120 square units
Solution: The standard deviation is used in conjunction with the mean to numerically describe distributions that are bell shaped. The mean measures the center of the distribution, while the standard deviation measures the spread of the distribution.
In normal distribution (bell shaped distribution) , the mean and standard deviation are used to describe its distribution. The mean measures the center of the distribution, while the standard deviation takes care of the spread of the distribution.
The mean of the normal distribution is and the standard deviation is

Answer:
19.95
Step-by-step explanation:
This is one of those questions that are a must do. The process is called estimation and if you follow it carefully, you learn a lot.
Round 19.95 to 20
Round 12.95 to 13 dollars. You get 15% off. which is about (1.50 + 0.75 = 2.25)
This the 10 pound bag down to 13 - 2.25 = 10.75. This is higher than 1 dollar per pound.
20 pounds for 20 dollars = 1 dollar per pound.
