The formula for perimeter is
Side a x2 + side b x2
So just multiply 18 by two, and subtract it from 108
Your answer is 3x^(2)+3x+6
Hope this helped!
Answer:
Hey, Something To help Check Out Symbolab its an online calc it has EVERYTHING thats how i do my math hope this helps
Step-by-step explanation:
We can adjust the data by adding 4 to everything before we calculate the statistics. Or we can calculate the statistics on the given data and just add 4 to everything at the end. We'll get the same answer either way.
Let's sort the seven data points: 5 5 5 7 7 9 10
Those add up to 48 so the mean is 48/7 = 6.9
The one in the middle is 7 so the median = 7
The mode is the most common one, mode = 5
The range is the difference between max and min, so range = 10 - 5 = 5
In the second week we add four to everything. Since that adds four to the min and max, the range doesn't change.
Answer: mean=10.9, median=11, mode=9, range=5
X = arctan(32/19)
x = 59.30 degrees.
You don't say if the answer needs to be rounded, so round it as needed.
