Answer:
Distributive Property
Step-by-step explanation:
They distributed the -3 to x and 4. In this case, to distribute the -3, you multiply it to each term.
-3 × x = -3x.
-3 × 4 = -12.
-3x - 12
The answer is 15.65.
I solve it below, to find the answer you only need to use the distance formula.
We can easily enumerate E and F:
The intersection is a set composed by all the element belonging to both E and F, i.e. 4.
The intersection of this set with D works in the same way, but it's actually a trivial one, since is a subset of D. In fact, D is the set of all integers, while 4 is a particular integer. And in general, if A is a subset of B, then the intersection between A and B is A itself, so the final answer is
Answer:
3x + 16/3
Step-by-step explanation:
3(x +1) + 2 1/3 (distribute 3 into parentheses)
3x + 3 + 2 1/3 (calculate)
3x + 5 1/3 (convert to improper fraction)
3x + 16/3 (done)
3x + 16/3
