C. trapezoid
a trapezoid's legs are congruent, while the bases are symmetrical
a square is the answer you would want, because it is always true, while a trapezoid is only "sometimes" true
thanks Kaikers :D
Answer:
x=20
Step-by-step explanation:
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B
Let's name the x-coordinates and y-coordinates
- x-coordinate = abscicca
- y-coordinate = ordinate
So, According to question
- Abscicca of Point D = Ordinate of Point B
- Ordinate of Point D = Abscicca of Point A
Abscicca of Point A = 2
Ordinate of Point B = -4
<h3>Thus, </h3>
Point D = (-4,2)
