Answer:
x+1 meters
Step-by-step explanation:
Area = Length * Width
x^2 - 6x - 7 = length * (x-7)
x^2 + x - 7x - 7 = length * ( x-7)
x*(x+1) - 7*(x+1) = length * (x-7)
(x-7)*(x+1) = length * (x-7)
x+1 = length [for (x-7) not equal 0]
The IQR tells you how spread out the "middle" values are. It can also be used to figure out if there are any outliers.
Step-by-step explanation:
<em>In the second column, we can see that every value of n is being added by 6. </em>
- Thus, the expression is n + 6.
<em>Now, let's substitute the value of n in each column to verify each column. Then, using the expression, let's find the value of n + 6 where n = 28.</em>
<u>When n is 12:</u>
- n + 6 = 18
- 12 + 6 = 18
- 18 = 18
<u>When n is 15:</u>
- n + 6 = 21
- 15 + 6 = 21
- 21 = 21
<u>When n is 21:</u>
- n + 6 = 27
- 21 + 6 = 27
- 27 = 27
<em>Thus, the expression is proven correct. Now, let's find n + 6 when n is 28.</em>
<u>Finding n + 6 when n is 28:</u>
- n + 6 = x
- 28 + 6 = x
- 34 = x
Thus, the missing value in the table is 34.
