Answer:
4x² - 9 is your answer dear.
Step-by-step explanation:
(2x+3) * (2x-3)
4x² - 6x + 6x - 9
4x² - 9
Hope you got it.
The first step is: subtracting 6 from both sides
Step-by-step explanation:
Given equation is:

the given equation is a linear equation in one variable.
The simple rules to solve equations are that any operation performed on one side of the equation is also performed on other side of the equation too.
So for the given equation, in order to isolate the variable x terms on one side first of all they will subtract 6 from both sides

Subtracting 3x from both sides

Hence,
The first step is: subtracting 6 from both sides

Answer:
A: ∠W'Z'Y' = 60°; angles aren't changed by rotation
B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)
Step-by-step explanation:
<u>Part A</u>:
Angle WZY is the supplement of the given angle ZWX, so is ...
∠WZY = 180° -120° = 60°
Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...
∠W'Z'Y' = 60°
__
<u>Part B</u>:
The transformation right 2 and up 3 can be described by ...
(x, y) ⇒ (x +2, y +3)
Then the translated vertices are ...
W(-5, 3) ⇒ W'(-3, 6)
X(7, 3) ⇒ X'(9, 6)
Y(6, -2) ⇒ Y'(8, 1)
Z(-6, -2) ⇒ Z'(-4, 1)
