Answer:
28 -4i
Step-by-step explanation:
Perhaps you want the product ...
(4 -2i)(6 +2i)
Multiplying in the usual way, we get ...
(4)(6) +(4)(+2i) +(-2i)(6) +(-2i)(2i)
= 24 +8i -12i -4i^2
Recognizing that i^2 = -1, we can collect terms to get ...
= 24 +i(8 -12) -4(-1)
= 28 -4i
_____
Please note that i = √(-1) is not the same as 1 or /. You may need to edit your question to ensure the correct symbol is used.
You can use a proportion
1/2(acres) 2(3/4)acres
-------------- = --------------
4(days) x(days)
4*2(3/4) = 6
6/(1/2) = 12
It would take 12 days.

Surface area= 2(6x15)+2(7x15)+2(6x7)
=180+210+84
=474m
Volume=15x6x7
=630m^2
The number of adult tickets and children tickets sold were 92 and 220 respectively
What differentiate adult tickets from children's
The adult tickets can be represented by a while children's ticket is c
The total number of tickets sold which is 312 means the sum of a and c
a+c=312
Total value of adult tickets=a*12
total value of children tickets=c*5
12a+5c=2204
Solve for a in the first equation
a=312-c
substitute for a in the second equation
12a+5c=2204
12(312-c)+5c=2204
3744-12c+5c=2203
3744-2203=12c-5c
1541=7c
c=1541/7
c=220
a=312-220
a=92
