Answer:
n=-2
Step-by-step explanation:
(2n−8)(−2)=24
(2n)(−2)+(−8)(−2)=24(Distribute)
−4n+16=24
−4n+16−16=24−16
−4n=8
Answer:
9
Step-by-step explanation:
divide 36 by 4 and its nine
We can check each of these using the Pythagorean Theorem,

Option A:

.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B

1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:

36 + 64 = 100
100 = 100
This option works
Option D:

9 + 16 = 25
25 = 25
This option works
So, after doing the calculations, we see that option B does not work
