<span>3x^2 + 4x + 8 + 2x^2 - 6x + 3 to give result as 9x^2 -2x - 5
</span>3x^2 + 4x + 8 + 2x^2 - 6x + 3
= 5x^2 - 2x + 11
so
9x^2 -2x - 5 - (5x^2 - 2x + 11)
= 9x^2 -2x - 5 - 5x^2 + 2x - 11
= 4x^2 -16
answer
expression (4x^2 -16) must be added to the sum of (3x^2 + 4x + 8) and (2x^2 - 6x + 3) to give the result as (9x^2 - 2x - 5)

Answer:
money owed (in order): $850, $870.40, $891.29, $912.68
Step-by-step explanation:
The formula is
money owed = amount owed the previous week + amount owed previous week × interest rate (in decimal form)
so thats:
money owed = amount owed the previous week + amount owed previous week × 0.024
we can simplify that to:
money owed = amount owed the previous week x (1.024)
after 0 weeks:
$850 (just started, no interest added)
after 1 week:
$870.40
after 2 weeks:
$891.29
after 3 weeks:
$912.68
Answer:
Step-by-step explanation:
u have an arithmetic sequence...ur adding 3 to every number to get to the next number
3 + 3 = 6
6 + 3 = 9
9 + 3 = 12
12 + 3 = 15
and so on...
median;
i tried mean 3, and mean 5 is wrong for sure, meaning it is median
explanation
arranged least to greatest
2, 2, 3, <em>3, 3,</em> 4, 4, 19 (8 numbers)
