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.
Answer:
-16-5i
Step-by-step explanation:
add real number together and imaginary numbers together
also, distribute the negative for the second parentesis
(14 -3i)-(20+2i)
distribute negative
14-3i-20-2i
add real and imaginary numbers
-16-5i
(2300 / 4500) * 100 = 51.1%
Hope this helps! :)
y - 5 = 3/2(x + 3)
y - 5 = 3/2x + 9/2
y = 3/2x + 9/2 + 5
y = 3/2x + 19/2

Answer:
60°
Step-by-step explanation:
sum of interior angles of quadrilateral is 360°
∠C = 70°
∠D = 50°
∠C + ∠D = 120°
∴ ∠A + ∠B = 360° - 120° =240°
AO and BO bisect ∠A and ∠B
∠OAB + ∠OBA = 1/2 x ( ∠A + ∠B) = 120°
∠AOB = 180° - (∠OAB + ∠OBA) = 180° - 120° = 60°
