Answer:
4(3x-y)
Step-by-step explanation:
Given:
To factor this kind of expression, first, find the common factor.
Notice that in the expression, we have both same (3x-y). Therefore, (3x-y) is our factor.
Let u = 3x-y
Change u back to 3x-y:
Therefore, the factored expression is 4(3x-y).

Answer: 130 meters
Step-by-step explanation:
We have to let the "surface of the ocean" be at 0 height.
So,
anything above surface has POSITIVE height
and anything below surface has NEGATIVE height
The albatross is 100 m above, so we can say its height is:
+100 meters
The shark is 30 m below, so we can say its height is:
-30 meters
The difference in height is thus:
100 - (-30) = 100 + 30 = 130 meters
Answer:
f(x) + g(x) = 
f(x) - g(x) = 
g(x) - f(x) = 
Step-by-step explanation:
Case 1:
f(x) + g(x)
= 
=
=
Case 2:
f(x) - g(x)
= 
= 
=
Case3:
g(x) - f(x)
= 
= 
=
