Answer:
Do not qualify
Step-by-step explanation:
Yearly income = $58000
Monthly income = = $4833.33
Median annual income = $47778
Monthly expenses = $4600
Income < Median Income ? 58000 < 47778 -> No
x = (Monthly income - expenses) * 60
= (4833.33 - 4600) * 60
= 233.33 * 60
= 13999.8
x < 10000 ? 13999.8 < 10000 -> No
So, Do not qualify
Answer:
see explanation
Step-by-step explanation:
This is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
16 = ( 4
)² ⇒ a = 4
1 = 1² ⇒ b = 1
Hence
16 - 1
= (4 )² - 1²
= (4 - 1)(4
+ 1)
4 - 1 ← is also a difference of squares and factors as
(2x² - 1)(2x² + 1)
Thus
16 - 1
= (2x² - 1)(2x² + 1)(4 + 1 )
