Answer:
because the area expression can be rewritten as
which equals 
Step-by-step explanation:
Area of the rectangle 

Since the length of a rectangle is 20 units more than its width.

The correct option is therefore 1.
When we say an amount increased by some percentage, we usually mean that percentage is added to the original amount. In symbols, if there were V visitors in 2003, then in 2005 there were
V + 200%×V = 3V
visitors. And in 2007 (after 2 more years), there were
3(3V) = 9V
visitors. This represents an increase of
(9V -V)/V × 100% = 800%
The number of daily visitors in 2007 was 800% more than in 2003.
Answer:
Step-by-step explanation:
Suppose pieces of chocolate pie served at a restaurant average 350 calories with a standard deviation of 20 calories. Calories have a Normal distribution due to inexact cutting of the pies. Which graph represents the proportion of pieces of pie that have more than 375 calories.
Answer: The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and for a negative z score means the raw score is below the mean. The z score is given as:

Given that: μ = 350 calories, σ = 20 calories, x > 375

From the graph, The shaded area represents the proportion of pieces of pie that have more than 375 calories
From the normal distribution table, P(x > 375) = P(z > 1.25) = 1 - P(z < 1.25)
= 1 - 0.8944 = 0.1056 = 10.56%
Answer: 8x + 14
Step-by-step explanation:
3x + 2 + 3x + 2 + x + 5 + x + 5 = 2(4x + 7) = 8x + 14
