Answer:
x=1.3288 or -1.1288
Step-by-step explanation:
Given 
Subtract 4x from both sides

Since we can factor out 2 from whole equation, let's factor out 2.

Divide with 2 on both sides

We got the quadratic equation, we can solve for x using quadratic formula.





Answer:
w = -10
Step-by-step explanation:
w + 4 = (-6)
Subtract 4 from each side
w+4-4 = -6-4
w = -10
Check the picture below.
so, as you can see, the UV segment is parallel to ZW, and therefore, they're the same slope, hmmm wait just a second, what is the slope of ZW anyway?

since now we know the ZW slope, we also know what is the slope for UV, thus,
Answer:
the shaded region is 12
Step-by-step explanation:
Subtract the area of 4 pie r squared from the area of 2 pie r squared
