Answer:
C
Step-by-step explanation:
If you are distributing, you must distribute the outside to both terms in the inside.
The two are perpendicular to each other because the two slopes are negative reciprocals
(Y2 - Y1) / (X2 - X1)
First slope:
( 1 - (-1)) / (-11 - (-6))
2/-5
Second slope:
(-13 - (-8)) / (-5 - (-3))
-5/-2 or 5/2
You know when two aliens are perpendicular when you multiply the two slopes and get -1 as the product
-2/5 X 5/2 = -1
Thus the two lines are perpendicular to each other.
I hope it’s helps i have to write more so I’m writing

Step-by-step explanation:
_______________________________
The problem given is:
_______________________________
Evaluate: log 2 base 8 .
_______________________________
Rewrite as: "
" ; 
_______________________
Take note of the following definition of a logarithm:
_______________________
"
" ; ↔ "
" ;
_______________________
in which:
refers to the "base" ;
refers to the "argument" ;
refers to the "exponent" ;
______________________________
As such:
"
"
⇔ "
" ; Solve for "x" ;
_______________
Note:
2⁰ = 1 ;
2¹ = 2 ;
2² = 2 * 2 = 4 ;
2³ = 2 * 2 * 2 = 8 .
___________________
→ "
" ;
→ "
" ; since: "
" ;
→ as such: " x = 3 " ;
______________________
Thus:
"log 2 base 8 " ;
=
.
