Answer:
The answer to your question is Width = 
Step-by-step explanation:
Data
Area = (x² - 4)/2 x in²
Length = (x + 2)² / 2 in
Width = ?
Process
1.- Write the formula of the area of a rectangle
Area = length x width
-Solve for width
Width = Area / length
2.- Substitute the values
Width = (x² - 4)/2 / (x + 2)² / 2
-Simplify
Width = (x² - 4) / (x + 2)²
-Factor both numerator and denominator
Width = (x - 2)(x + 2) / (x + 2)(x + 2)
- Simplify
Width = (x - 2) /(x + 2) or Width =
The cost of one pencil is $10:8=$1.25
The cost of 20 pencils: 1.25 x 20 = $25
It's January, they have till July => 6 months including January
half of $8000 is $4000 in 6 months
4000/6 = $666.66 per month

Answer:
Step-by-step explanation:
Step 1: Find what adds to _ and multiples to_
It needs to multiple to the 'c' term or 9
It needs to add to the 'b' term or -10
Step 2: Find the numbers
We know -9 and -1 make 10 and multiple to 9
-9 x -1 = 9
-9 + (-1) + -10
Step 3: Write equation in form a(x-r)(x-s)
a = 1
r = -9
s = -1
Plug in the equation to get the factored form of the equation:
Therefore the factored form of the equation is
