Find the term that must be added to the equation x2+4x=1 to make it into a perfect square
Vsevolod [243]
<h3>You need to add 4 to both sides</h3>

The x term has a coefficient of 4. Take half of this to get 2, then square it to get 4. This is the value we add to both sides to get x^2+4x+4 = 5. Note how x^2+4x+4 factors into (x+2)^2

---------

Another example: Let's say we started with x^2+6x = 1. To complete the square, we need to add 9 to both sides. I start with 6 (the x coefficient) and cut that in half to get 3, then I squared that to get 9. So we add 9 to both sides getting x^2+6x+9 = 10 which becomes (x+3)^2 = 10

End of second year = 669.50+19.5 = $ 689

End of third year = 689+19.5 = $708.50

End of fourth year = 708.50 +19.5 = $ 728

During a radio contest, $50 is added to the prize money each time a caller answers the contest question incorrectly. The first
Gnoma [55]

Answer:

The expression is  a_{10} = 100+(10 - 1)50 .

Step-by-step explanation:

Given as :

The amount of money added as prize money =  $50

The amount that first caller will win =  a_{1} = $100

Let The amount that 10th caller win = $A

∴ common difference for the callers amount = $50

Now, According to question

<u>The given statement is in arithmetic expression</u>

So, For A.P , The nth term is written as

nth term = first term  + (n - 1) × common difference

I.e a_{10} = a_{1} +  (n - 1) × common difference

Here n = 10

Or, A = $100 +  (10 - 1) × 50

So, The expression =  a_{10} = 100+(10 - 1)50

Hence, The expression is  a_{10} = 100+(10 - 1)50 . Answer
