Answer:
5x - 5
Step-by-step explanation:
To find the missing side, add the two sides together and subtract them from the perimeter.
side 1 + side 2
3x + 2 + 8x + 7
combine like terms
11x + 9
Subtract from the perimeter
16x + 4 - (11x + 9)
rewrite as an addition problem, so you need to change the signs inside the parentheses.
16x + 4 + (-11x -9)
Now combine like terms
5x - 5
Answer:
B, irrational
Step-by-step explanation:
We know that π is irrational, since it can not be written as a division between natural numbers (a sub class of Real numbers called N), it's value is 3,1415(a whole bunch of decimals after this)
If you remove the decimal part of π by subtracting the integer part of it, that is the number 3. the result will still being and irrational number
Since π= 3(the rational part) +0,1415... (the irrational part)
The resut of π-=3= 0,1415...

Answer:
The range is 4
Step-by-step explanation:
<u>To find the range, you subtract the lowest number from the highest number.</u>
<u />
<u>Example: If the set was: 1, 2, 6, 6, 8, 10</u>
What is the highest number: 10
What is the lowest number: 1
<em>You will do this -> 10 - 1 = 9</em>
<em />
<u>Problem: 8, 9, 9, 8, 8, 5, 8</u>
What is the highest number: 9
What is the lowest number: 5
<em>9 - 5 = 4</em>
<em />
Answer: The range is 4
