Answer:
Step-by-step explanation:
16x⁸ - 81y⁸ is the difference of squares.
16x⁸ - 81y⁸ = (4x⁴)² - (9y⁴)² = (4x⁴ + 9y⁴)(4x⁴ - 9y⁴)
Note that 4x⁴ - 9y⁴ is also the difference of squares.
4x⁴ - 9y⁴ = (2x²) - (3y²)² = (2x² + 3y²)(2x² - 3y²)
16x⁸ - 81y⁸ = (4x⁴ + 9y⁴)(2x² + 3y²)(2x² - 3y²)
Answer:
$7.7
Step-by-step explanation:
Step one:
given data
total money = $175
He buys 4 shirts for $24 each= 24*4= $96
The shirts are discounted 20%
= 96- 0.2*96= 96-19.2= $76.8
2 pairs of shorts for $18 each= $36
2 pairs of pants for $22.50 each= $45
Total cost = $157.8
tax= 6%
total expenses
= 157.8+ 0.06*157.8
=157.8+9.468
=$167.268
The balance is
= 175-167.268
=$7.7
