Answer:
The pre-image of the quadrilateral is attached.
Step-by-step explanation:
Each point (x, y) is rotated with the rule (x, y) -> (-x, -y).
So, point W'(2, 3) was W(-2, -3) before rotation.
X'(6, 3) was X(-6, -3)
Y'(6, 4) was Y(-6, -4).
Z'(3, 5) was Z(-3, -5).
The pre-image of the quadrilateral is attached.
Calculating the area and the perimeter The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
Answer:
2 real solutions
Step-by-step explanation:
Since the degree of the polynomial is 2, then there are 2 solutions for the equation, but we don't know if they are both complex or both real.
Since the discriminant is
, then there are 2 real solutions.

Answer:
x = 2, -1
Step-by-step explanation:
x² - x + 1 = 3
- 3 -3
x² - x - 2 = 0
(x -2)(x + 1)
