(3x + 2)(3x - 2)
Expand,
= 9
- 6x + 6x - 4
Combine like terms,
= 9
- 4
Therefore, your answer is C!
Hope this helped!
The sum of the three interior (inside) angles of a triangle sums up to 180°. This is stated by the Triangle Sum Theorem.
Answer:
x = 8
Step-by-step explanation:
Since we know that the 2 triangles are similar (AA Similarity), we find the ratio of Triangle PLM: 2
We then multiply 4 by 2 (the ratio) to get x = 8 as length JK.
Answer: Choice B) -5.2 degrees
=====================
Work Shown:
Add up the given temperatures
-42 + (-17) + 14 + (-4) + 23 = -26
Then divide by 5 since there are 5 values we're given
-26/5 = -5.2
