Answer:
C
Step-by-step explanation:
King Snake: 65 inches / 12 inches per foot = about 5.4 feet long
Eastern Diamondback Rattlesnake: 2 yards * 3 feet per yard = 6 feet long
Ridge Nosed Rattlesnake: 4 feet long
Therefore, the eastern diamondback rattlesnake is the longest snake.
Remark
This is like using the distributive principle only you are going backwards. Instead of trying to remove brackets, you are trying to create them.
Solution
Since you want to take - 6 outside the brackets you should divide both terms by - 6
<em><u>- 18a</u></em>: - 18a/- 6 = 3a which is left inside the brackets.
<em><u>-30:</u></em> - 30/-6 = 5
- 6(3a + 5)
Answer
-6(3a + 5)
Part A: Factor 3x2y2 − xy2 − 2y2. Show your work. (4 points)
3x^2y^2 − xy^2 − 2y^2
y^2 ( 3x^2 - x -2 )
y^2 (3x+2)( x - 1)
Part B: Factor x^2 + 6x + 9. Show your work. (3 points)
x^2 + 6x + 9
= x^2 + 2*3x + 3^2
= (x+3)(x+3)
= (x+3)^2
Part C: Factor x2 − 25. Show your work. (3 points)
x^2 - 5^2

Answer:
x = 18
Step-by-step explanation:
The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.
So, 20/8 = (4x + 3)/30
8(4x + 3) = 20(30)
32x + 24 = 600
32x = 576
x = 18
