X^2 - 8x = (x - 4)^2 - 16
we add 16 to give x^2 - 8x + 16 which is a perfect square
x^2 - 8x + 16 = (x - 4)^2
answer is 16
The solutions of the absolute value equation is determined as 15 and - 5.
<h3>Solution to the absolute equation</h3>
The solution to the absolute equation is determined as follows;
|x - 5| + 7 = 17
<em>collect similar terms</em>
|x - 5| = 17 - 7
|x - 5| = 10
<em>to resolve the absolute values, form two equations as follows;</em>
x - 5 = 10 and x - 5 = -10
x = 15 and x = -5
Thus, the solutions of the absolute value equation is determined as 15 and - 5.
The complete question is given as;
|x - 5| + 7 = 17

Answer:
-5
Step-by-step explanation:
<u>Given that , </u>
- A number is taken away from 40 and the result is 45 .
<u>L</u><u>et </u><u>:</u><u>-</u><u> </u>
- The required number be x .
<u>According</u><u> to</u><u> Question</u><u> </u><u>:</u><u>-</u><u> </u>
40 - x = 45
- x = 45 - 40
- x = 5
x = -5
<h3>
Hence the required answer is -5 .</h3>
