What is the solution of -(x + 1) - 5 > 10
Pie
<span> -(x + 1) - 5 > 10
 -x - 1 - 5 > 10
 - x - 6 > 10
Add 6 to the both sides, 
-x - 6 + 6 > 10 + 6
-x > 16
x < -16  [ changed sign 'cause changed -sign ]

In short, Your Answer would be x < -16

Hope this helps!</span>

Write a simplified polynomial expression in standard form to represent the area of the rectangle below.
Burka [1]
Area of Rectangle = length times width
lets say length = 2x-4
width = x+5

Note: you can switch these around, width could be 2x-4 and length could be x+5, it doesnt matter.

With that being said:
length * width = area
(2x-4)(x+5)=area
FOIL (First Outer Inner Last)
2x^{2}+10x-4x-20=area
Simplify:
x^{2}+6x-20=area
