Step-by-step explanation:
Perimeter of Rectangle ABCD = 
Perimeter of Rectangle PQRS = 
Difference between perimeter of Rectangle ABCD and Perimeter of Rectangle PQRS:

Open Parentheses

Collect like terms


Answer:
First is 
Second is
Step-by-step explanation:
Open up equations and do FOIL method.
First equation:
(x + 2y)(x + 2y)
x^2 + 2xy + 2xy + 4y^2

Second equation:
(y + 2x)(y + 2x)
y^2 +2xy + 2xy + 4x^2

Answer:
see attached
Step-by-step explanation:
The equation can be rewritten to vertex form, so you can tell the vertex is at (2, -5). The leading coefficient of 2 means the points will be twice as far apart vertically than they would be if the leading coefficient were 1. A couple of points are shown in the attached.
y = 2(x^2 -4x) +3
y = 2(x^2 -4x +4) +3 -8 . . . . . . complete the square
y = 2(x -2)^2 -5 . . . . . . . . . . . . finish putting in vertex form
Answer: 6 days
Step-by-step explanation:
if you make them into common denominators, it would be 6/8, so it would last 6 days
