The first picture represents the elements in B that are not (also) in A. So, we want the set difference of B and A:
For the second picture, we can work like this: if we take all the elements belonging to A, we only need to add the bottom-right part, which is the intersection of B and C. So, we can express the blue part as
Answer:
x - y = 0
Step-by-step explanation:
The given line is y = x.
We could re-write this as x - y = 0, which is in general form.

Answer:
0.512a³ cubic units
Step-by-step explanation:
Given a cube of length, a, then when decreased by 20%, what's left is actually 80% of the original. So, for this case, we have a cube with a length of 80%(a) = 0.80a.
Now, to compute for the volume of a cube, we multiply the length three times to itself. Or, in other words, raise the length to the third power. That means the volume of the new cube is (0.8a)³ = 0.512a³ cubic units.
Find 1 1/4 on the number line and count back 3/4 (why it is negative) answer is 1/2.
