Answer:
25
Step-by-step explanation:
The number that needs to be added is the square of half the x-coefficient:
(-10/2)^2 = 25
_____
Adding that gives ...
(x -5)^2 = 32
x = 5 ± 4√2
After manipulating above equation we get, 2x^2 - 7x - 8= 0. Discriminant= b^2 - 4ac = (-7)^2 - 4(2)(-8) = 113>0. So there are 2 real roots :)
Answer:
-9/5
Step-by-step explanation:
Step 1: Take the LCM in the denominator
6/5-3
multiply the numerator and denominator by 5 to make the denominator 5.
<u>6</u>-<u>3</u> (x5)
5 1 (x5)
=<u>6-15</u>
5
= <u>-9</u>

I don’t know the answer but I can tell you how to do it subtract starting value minus final value divide that amount by the absolute value of the starting value multiply by 100 to get percent decrease if the percentage is negative it means there was an increase not a decrease

I was a little stumped too, but I think this is it. That's my work process, though
