100% correct don't worry ;)
Step-by-step explanation:
6 & 5 and 2&3 are the adjacent angles
Answer:
3(2 - y)(2 + y)(4 + y²)
Step-by-step explanation:
48 - 3y⁴
Take 3 common:
3(16 - y⁴)
16 is 4² and y⁴ is (y²)²
3(4² - (y²)²)
Using a² - b² = (a - b)(a + b)
3(4 - y²)(4 + y²)
Again, 4 = 2²
3(2² - y²)(4 + y²)
3(2 - y)(2 + y)(4 + y²)
Gratuity is the total tip given.
The tip is directly proportional to total cost:
18/0.20 = x/1.00
$90
