<h3><u>Answer</u> :</h3>
★ (x² + 6x - 5) + (2x² + 15)
➠ x² + 6x - 5 + 2x² + 15
By combining similar terms, we ge
➠<u> x² + 2x²</u> + 6x - <u>5 + 15</u>
➠ 3x² + 6x - 10
By taking 3x common, we get
➠ 3x(x + 2) - 10

Answer:
When the solution is negative
Step-by-step explanation:
One example, let's say you are buying pens and each pen cost 3 dollars and you cannot spend more than 15 dollars, how many pens can you buy?
The inequality would be 3x < 15, so any negative solution is not reasonable because you cannot buy negative pens. The same goes for most real-world problems dealing with time, money, or distance.
Represent these consecutive numbers (assuming that they are all integers):
x
x+1
x+2
x+3
x+4
x+5
and so on
x+8
x+9 is the tenth number. x+9 = 10, so x = 9.
Think of it this way: there are 10 consecutive numbers, and the last one is 10.
Working backwards, we get the sequence 10, 9, ... 3, 2, 1.
The sum of such an arith sequence is equal to the count of the numbers times the average of the first and last terms:
sum here = 10(1+10)/2 = 5(11) = 55 (answer)
I think its 4910.00 you can't make a whole number a decimal.
