Answer:
- 3 packages of cups
- 4 packages of napkins
Step-by-step explanation:
You need at least enough for 60, so any requirement for a partial package means you need to buy another whole package. The "ceiling" function gives the next higher integer for a non-integer value.
cups = ceiling((60 cups)/(24 cups/package)) = ceiling(2.5) packages
= 3 packages
__
napkins = ceiling((60 napkins)/(18 napkins/package))
= ceiling(3 1/3) packages = 4 packages
Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
3x-x=(2x+4)-(x+4)? That is my answer but it might not be right

Thanks for free points :)
Parentheses first, 72-63 is 9 next multiply by 4 which is 36 the you’ll divide by 3 now you have 12 so multiply that by 6 and you get 72. Just a hint, another way to write that without using the multiply or the divided would be 6[4(72-63)/3] but either way you want is fine. Hope this helped :)
