Step-by-step explanation:
13.6 is the answer because 1cm is 10 cm
-9-6i/-3-2i
Factor -3 out of expression
-3(3+2i)/-3-2i
Then extract the negative sign out of the expression
-3(3+2i)/-(3+2i)
Reduce the fraction with -(3+2i)
-3/-1
-3*-1=3
Hope this helps

5-(2.18+1.65)
Answer:
6
Step-by-step explanation:
27/4= 6 3/4
That doesn't work because we need whole numbers.
24/4=6
That is the solution. For $24 we buy 6 tubes for $4 each and we have $3 left over.
Formula for are of a rectangle:
A =L * W
1st isolate W
147 = 3W * W
147 = 3W^2
divide 147 by the by 3 on bot sides
29 = W^2
get ride of the square by square rooting on both sides
7 = W
2nd find the perimeter
P = 2(7) + 2(21)
P = 14 + 42
P = 56
