That the answer Plss follow me thanks
Answer:
Find the prime factorization of 30
30 = 2 × 3 × 5
Find the prime factorization of 66
66 = 2 × 3 × 11
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the lcm:
LCM = 2 × 3 × 5 × 11
<em>LCM = 330</em>
<em></em>
<em>* Hopefully this helps:) </em>
Easily done! Just do -56 divided by -7 but just remember two negatives equal a positive. So your answer would be 8!
Answer: 9
Step-by-step explanation:
27 divided by 3 is 9 so 9 is the constant variation

Answer: D) 130 </h3>
========================================================
Explanation:
The three upper angles
all combine together to form a 180 degree straight angle. Let's add up the angle expressions and set the result equal to 180. That will help us solve for x.
(angle AOB) + (angle BOC) + (angle COD) = 180
(3x-28) + (90) + (66-x) = 180
2x+128 = 180
2x = 180-128 .... subtract 128 from both sides
2x = 52
x = 52/2 .... dividing both sides by 2
x = 26
Since x = 26, we can find the missing angles like so
- angle AOB = 3x-28 = 3*26-28 = 50
- angle COD = 66-x = 66-26 = 40
Note how:
(angle AOB) + (angle BOC) + (angle COD) = 50+90+40 = 180
to help confirm we have the correct x value.
--------------------------------------
Afterward, we need to find angle BOD which is the combination of angles BOC and COD
angle BOD = (angle BOC) + (angle COD)
angle BOD = 90 + 40
angle BOD = 130
Angles BOD and AOE are vertical angles. It might help to erase ray OC so you can see the two vertical angles better. Vertical angles are always congruent, which means angle AOE is 130 degrees as well.
