Mathematics
1 answer:
Leokris [45]4 years ago

Answer:

D. 25x² - 20x + 4

Step-by-step explanation:

The formula for the area of a square is: A = s², where s = a side length of the square since all side lengths of a square are equal.  In this case, the side length is represented by '5x', so the original area is A = (5x)² = 25x².

Since Kelly is cutting off one inch from each side of square, this will actually take off 2 total inches from each side, making the new side length '5x - 2'.  We can now put this expression in for the values of 's' in our formula for area and use distributive property to solve:

A = (5x - 2)² = (5x - 2)(5x - 2)

Distribute using FOIL:  25x² - 10x - 10x +4 or 25x² - 20x + 4

Victoria’s printer can print 8.804 in one minute if Victoria’s prints page for 0.903 minutes, about how many pages will she have
SVETLANKA909090 [29]

Victoria’s printer can print 8.804 in one minute if Victoria’s prints page for 0.903 minutes,

We apply unitary method

In one minute the number of pages printed is 8.804. we need to find the number of pages for 0.903 minutes

1 minute = 8.804 pages

0.903 minutes = ? pages

We multiply 8.804 by 0.903

8.804 * 0.903 = 7.95

Number of pages printed = 7.95 pages

Answer me if you need a friend<br><br> Also 5x+25=35<br><br> x=
STALIN [3.7K]

Answer:

x = 2

Step-by-step explanation:

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 25 from both sides of the equation:

5x + 25 (-25) = 35 (-25)

5x = 35 - 25

5x = 10

Isolate the variable, x. Divide 5 from both sides:

(5x)/5 = (10)/5

x = 10/5

x = 2

x = 2 is your answer.

Help quickly! A student wants to report on the number of movies her friends watch each week. The collected data are below:
max2010maxim [7]
1.The measure of center that is most appropriate for this situation is the MEDIAN. This is because, one of the number given is an outlier, that is, it is much greater than the rest of the given numbers. If the mean of the number given is calculated, it will be discovered that the mean value obtained is higher than most of the scores in the data set, thus,the mean is not a suitable measure of central tendency in this case.
2. To find the median of the given numbers, arrange them in a descending order and add the two numbers in the middle then divide the value by 2.
That is, 0, 0, 1, 1, 2, 2, 2, 14.
The two numbers in the middle is 1 and 2.
 Median = [1 + 2] / 2 = 3/2 = 1.5
Therefore, the median is 1.5
