Answer:
(A - B) - C = { 1 , 4 , 6 , 7 }
Step-by-step explanation:
A = { 1 , 2 , 3 , 4 , 5 }
B = { 4 , 5 , 6 , 7 }
A - B = { 1 , 2, 3 ,6 , 7 }
C = { 2 , 3 , 4 }
First, we expand the equation using the distributive rule:
Hence,
Simplify:
Add like terms:
Subtract 13 from both sides:
Divide both sides by -8:
Do not get grounded.
An angle at a point is 360°.
So,
there arent
Δ is negative
