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
It says describe the perimeter with your own words, so what perimeter?
To find the volume of a cylinder you would multiply pi, radius squared, and height.
r= 6 ft
h= 2 ft
pi= 3.14
First you want to square your radius, so you would do 6 times 6.
This gives you 36.
Now you just multiply by 3.14 and get 113.04, then multiply that by 2.
Your final answer is 226.08ft³
If you need further explanation, just let me know! :)
One pint would be the answer because a pint in 16 oz
