Use the zero product property to find the solutions to the equation x2 – x – 6 = 0.x = –3 or x = –2
x = –3 or x = 2
x = –2 or x = 3
x = 2 or x = 3

Δ = b² -4ac = (-1)² -4·1·(-6) = 1 + 24 = 25
x₁= (-b + √Δ)/(2a) = (1 + √25)/2·1 = (1+5)/2 = 6/2 = 3
x₂= (-b - √Δ)/(2a) = (1 - √25)/2·1 = (1-5)/2 = -4/2 = -2
x=3 or x=-2
we know that
The Zero Product Property states that if , then either
or
(or both)
we have
rewrite the expression
so
therefore
the answer is the option
x = –3 or x = 2

m2WXY < m_YZX
m2WXY + m2YXZ = 180°
m2WXY + m_XYZ = 180°
Answers
The correct statement is,
⇒ m ∠WXY + m ∠YXZ = 180°
What is mean by Angle?
An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
To find the correct statement.
Now, We can find the correct statement as;
By definition of linear pair we get;
⇒ m ∠WXY + m ∠YXZ = 180°
Thus, The correct statement is,
⇒ m ∠WXY + m ∠YXZ = 180°

Answer: C. angle WXY + angle YXZ = 180 degrees
Explanation:
These two angles are a linear pair. They are supplementary (ie they add to 180) and they are adjacent. We know they are supplementary because line WXZ is a straight line. Put another way: point X is on line WZ.
-------
Side notes:
- Choice A is only true if we have a 90 degree angle at point X
- Choice B is never true because of the remote interior angle theorem
- Choice D is only true if we have an isosceles triangle with XZ = YZ.

34=2X + 2(2)
34= 2X + 4
30 = 2X
15 = X
the current answer is... 15
use the formula for the perimeter and solve for L:
34 = 2L + 2(2)
34 = 2L + 4
30 = 2L
15 = L

if you have 2 parts and 2 are needed to make 1 whole, then you have 1 whole since
x/x=1 where x=x
it would be only 1
