Answer:
Step-by-step explanation:
16 = 2 *2 * 2 * 2 = 2⁴
16y⁴ = (2y)⁴
x⁴ - 16y⁴ = x⁴ - (2y)⁴
= (x²)² - [ (2y)² ]²
{Use identity = a² -b² =(a +b)(a- b). Here a =x² & b =(2y)²}
= (x² + (2y)² ) (x² - (2y)² )
= (x² + 4y²) (x² - 4y²)

Answer:
You'll need $2,500 in sales this week to end up with $600 in income for the week.
Step-by-step explanation:
Let s represent the dollar amount of the total sales for the week.
The commission earned on such sales is 1/5, or 0.20, of s:
Commission: 0.20s
Then the correct expression for your weekly income is:
$100 + 0.20s = $600.
Solving for s, subtract $100 from both sides. Then 0.20s = $500, and through division we get s = $2,500.
You'll need $2,500 in sales this week to end up with $600 in income for the week.
