Answer: (a-2b)3=3a-6b
=3x-2-6x-1/2
= -6+3
= -3
Step-by-step explanation:
Simplifying
12x + 10 + 3 + 8x = 0
Reorder the terms:
10 + 3 + 12x + 8x = 0
Combine like terms: 10 + 3 = 13
13 + 12x + 8x = 0
Combine like terms: 12x + 8x = 20x
13 + 20x = 0
Solving
13 + 20x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 20x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 20x = 0 + -13
20x = 0 + -13
Combine like terms: 0 + -13 = -13
20x = -13
Divide each side by '20'.
x = -0.65
Simplifying
x = -0.65
Answer:
<6
Step-by-step explanation:
Corresponding angles have the same matching corner.
<6 has the same matching corner as <2. <6 and <2 are congruent.
Therefore, it can be concluded that <6 corresponds to <2.
