Answer:
Hey the answer is one.
Step-by-step explanation:
There is a quizlet with 18 of the answers with explanations on it just type in the unit subject and this question and it should pop up.
But on a side note,
I don't know who deleted my answer last time but I was giving you a resource to use if you want to learn the full step by step explanation look on your lesson videos or ask your teacher. This site i have found lets people give one another answers so unless this person and some army is planning on stopping everyone from giving answers i think they should just stop using this site.
Answer:
(2x+1)(2x−1)
Step-by-step explanation:
Use this formula:

a) d=11
Work:
d=sqrt((4-(-7))^2+(5-5)^2
d=sqrt((11)^2+(0)^2)
d=sqrt(121+0)
d=sqrt(121)
d=11
b) d=4
c) d = 16
d) d=160
e) d=12
Answer: B. No slope
Explanation: The slope of a perpendicular line will always be the negative reciprocal of the slope of the given line. That means that you first have to find the slope of the given line by using the two points on that line:
Point 1: (-5, 4)
Point 2: (-2, 4)
Slope=(y2-y1)/(x2-x1)
Slope=(4-4)/((-2)-(-5))
Slope=0/3
If the slope of the initial line is 0/3 and the slope of its perpendicular line is the negative reciprocal of that slope, that means the slope of the perpendicular line will be -3/0 which is undefined because you can’t divide -3 by 0.
Therefore, the slope of the perpendicular line is undefined, or in other words, there isn’t an exact slope.
Hope that helps シ
