Answer: - 2x^2 + 4x + 3
Step-by-step explanation:
( -x^2 - 4x - 5) + ( -x^2 + 8x + 8)
Take out parentheses:
- x^2 - 4x - 5 - x^2 + 8x + 8
Write in a way so that like terms are grouped together:
- x^2 - x^2 - 4x + 8x - 5 + 8
Combine 'x^2' terms:
- 2x^2 - 4x + 8x - 5 + 8
Combine 'x' terms:
- 2x^2 + 4x - 5 + 8
Combine integers:
- 2x^2 + 4x + 3
Answer:
For the pre-rax subtotal x you have this equation
x + 0.074x = 408.12 dollars.
x*(1 + 0.074) = 408.12
1.074x = 408.12 ====> x = 408.12%2F1.074. 408.12/1.074
Step-by-step explanation:
Please, you need to help yourself by looking up the meaning of these terms: mean, median, mode, range FIRST. How else will you know what you're looking for?
Example: Find the mean of the integers 34 33 35 33 32 35 34 32. To do this, just add them up, count how many you have, and then divide your sum by that count.
Example: Find the median of the integers 34 33 35 33 32 35 34 32. First, arrange these integers in ascending order: 32 32 33 33 34 34 35 35. Second, count them: I see 8 integers. Third, find the median: It's the average of the middle two integers: (33+34)/2 = 33.5
