The answer would be A because if you combine all the like terms you will get A as a result.
-2x^2+8x-9+4x+7x^2+2
-2x^2+7x^2 combine both of these and it will get you 5x^2
And then you would do 8x+4x which would be 12x and lastly you would -9+2 which would be -7 so the answer is A.
Hope this helps!!

Answer:
35 People
Step-by-step explanation:
From the given information
- $125 was charged for the rental of the hall
- Each Meal costs $12
- Total Bill = $545
Let the number of people attending the banquet=x
Therefore:
Cost of Hall Rental + Total Meal Cost = Total Bill
125+12x=545
12x=545-125
12x=420
x=420/12=35
Since x=35, we conclude that 35 People attended the banquet.
2290.22mm^2

Answer:
= n² - 2
Step-by-step explanation:
Consider the differences between the values
- 1 , 2 , 7 , 14 , 23
3 5 7 9 ← not constant
Now consider the difference of these differences
3 , 5 , 7 , 9
2 2 2 ← constant
Since the second differences are constant, this indicates a quadratic n²
Now consider the position values of n
n = 1 : 1² = 1 ← require to subtract 2 for - 1
n = 2 : 2² = 4 ← require to subtract 2 for 2
n = 3 : 3² = 9 ← require to subtract 2 for 7
n = 4 : 4² = 16 ← require to subtract 2 for 14
n = 5 : 5² = 25 ← require to subtract 2 for 23
Thus n th term formula is
= n² - 2
