3^2 = 9 = 4+5
5^2 = 25 = 12+13
work:
If you want to write an odd number as the sum of two consecutive integers, just subtract 1 then divide by 2 and you'll get the first integer.
Like with 25: first subtract 1 and get 24. Then divide by 2 and get 12. So the integers are 12 and 13.
Answer:
The answer to your question is below
Step-by-step explanation:
(2x⁴ + 7x³ - 3x + 9) - (6x⁴ - 3x³ - 6x² - 17)
Step 1. take out the parenthesis, in the second term, change the signs
2x⁴ + 7x³ - 3x + 9 - 6x⁴ + 3x³ + 6x² + 17
Step 2. Group like terms
(2x⁴ - 6x⁴) + (7x³ + 3x³) + (6x²) + (-3x) + (9 + 17)
Step 3. Simplify like terms
-2x⁴ + 10x³ + 6x² - 3x + 26
Correct answer; A right angle
Two thousand dollars is invested at 5.5 percent interest compounded
quarterly for 2 years. Then the amount is $ 2230.88
<u>Solution:</u>
Given that Two thousand dollars is invested at 5.5 percent interest compounded quarterly for 2 years
<em><u>The formula for amount using compounded quarterly is given as</u></em>:

Where, "p" is the principal sum
"R" is the rate of interest
"T" is the number of years
Here in this problem,
P = 2000 ; R = 5.5 ; T = 2 years
Plugging in values in formula we get,


On solving we get,

Hence the amount is $ 2230.88
