It is true due to the commutative property of multiplication. If all of your operations are multiplication, then the integers can move around and you can still get the same answer. 
^This is only true if you meant to type (1.8x3)x2.1=(1.8x2.1)x3

If you meant what you typed, then the equation is false. The left side would be 3 times the value of the right side due to the 3 being on the left side and not the right side while without the 3 the two sides would be equal.

Find the measure of the angle indicated. Find m UTW
Ghella [55]
You would find the measure of angle U which is 33. Then you would add 8x+12x and get 20x then you would add 33 and 7 and get 40 so you have 20x+40=180 (because all of a triangles measures = 180) then you would minus 40 from both sides you now have 20x=140 then divide by 20 and x=7 then you would go back and do 12(7) . Then your angle = 84
