Solve for x in the equation x^2 - 14x + 31 = 63?
<h3><u>Answer:</u></h3>
The value of x for given equation is x = 16 or x = -2
<h3><u>Solution:</u></h3>
Given that equation is
To find: value of "x"
<u>Subtract 63 from both sides we have:</u>
Now we will factor our given quadratic equation by splitting the middle term.
-14x can be splitted as -16x + 2x
<u>Take "x" as common from first two terms and "2" as common from last two terms</u>
<u>Take (x-16) common we have:</u>
Equating the terms to 0,
x - 16 = 0 or x + 2 = 0
x = 16 or x = -2
Therefore, the value of x are: 16 and -2
Answer:104.04
Step-by-step explanation:
20 inches... the area of the small window is 20^2 which is equal to 400. Therefore the bigger window is 25 inches long and the area of the bigger window is 625 inches^2. Add these areas together to get 1025 in^2
Answer:
$1040
Step-by-step explanation:
Firstly, we must lay down all the details given..
●The price increased by 30% that means that the original price which was 100% is now 130%
●The present price which is the original price for now is 100%.
One way we can show these details is by mathematical term, proportional method.
So,
100%= $800
1%=800÷100
130%= 800÷100×130
= $1040
Hope it helps!
