Answer:

Step-by-step explanation:
Given
See attachment for her sketch
Required
Which equation do not represent the perimeter
From the attached sketch:
--- Length
--- Width
Perimeter (P) is calculated as:

This gives:
---- This represents (A)
Open bracket
---- This represents (B)
In algebra:
means 
So, the expression becomes
--- This represents (D)
<em>This implies that (C) does not represent the perimeter</em>
Answer:
2
Step-by-step explanation:
(x - 5)^2 =
(x - 5)(x - 5) =
x^2 - 5x - 5x + 25 =
x^2 - 10x + 25 <===
It will be $2.50 for each pound of walnuts, and it will be $1 for each pound of chocolate chips.
I know this hold true because when we multiply $2.50 by 2, we get $5, and add that to the other $5 from the chocolate chips and we will get $10. We can also multiply $2.50 by 8 and add $3 from chocolate chips to get $20 + $3, or $23.
What does a standard deviation of 0 indicates 0.
