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>
Y = 2x² + 30x + 200
y = 2(x² + 15x + 100)
x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10
200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)

Answer:
Decrease
Step-by-step explanation:
50 is bigger than 20, so it's decreasing and the units are the same.
To find the volume of the computer, we just have to multiply each coordinate.
<h2>Hence, the volume is 32.4 cubic inches.</h2>
the equation 2x-4-1+x would be the answer
Because 2x+x = 3x and -4-1 = 5, the result would be 3x-5
