Answer:
D. 28 +10i
Step-by-step explanation:
As with any "collect terms" problem, you first identify the like terms, then add their coefficients. You can start with either the real or the imaginary terms to obtain a result that will point you to the correct answer choice. Of course, the distributive property works in the usual way.
(3i+ 4) -i + 4(6 +2i) = 3i +4 -i +24 +8i . . . . eliminate parentheses
= (4 +24) +(3 -1 +8)i . . . . . . . group like terms
= 28 +10i
Answer:
C = 40.2124
Step-by-step explanation:
The formula for circumference is
C = 2*pi*r
where r is the radius.
Substitute what we know.
C = 2 * pi * 6.4
C = 12.8 * pi
If we use substitute pi in, we get
C = 40.2124
Answer:
Step-by-step explanation:
We are given the following in the question:
Let P be the number of professor and S be the student in a college.
According to the question:
There are 19 times as many students as professors.
We have to write an equation to show the given relationship between professors and students.
The above situation is the situation that represents the given relationship.
C because it's using the distributive property. It's breaking it down into sections.
