Answer:
Step-by-step explanation:
Givens
L = 5
w = 3
Formula
Area = L*w
Solution
Area = 3 * 5
Area = 15
Now double both the width and the Length.
New Length = 2*5 = 10
New Width = 2 * 3 = 6
Area = New Length * New Width
Area = 10 * 6
Area = 60
Answer (look at the choices)
The old rectangle has an area of 15. The new Rectangle has an area of 60. If you double 15, do you get 60. No, so the answer is not A
The new rectangle is 60. If you halve it, do you get 15. No so the answer is Not B
C is the answer
D is you multiply 8 * 15, do you get 60? No so the answer is not D
The third one is a point with the first equation.
I had to simplify the second equation.
It simplified to,

The second one with the above is didn't go through so I'd say no solution.
Answer:
-9i. if 6 plus 3 = 9 and the six was a negative plus a positive 3 it's -9 and the 3 had any I attached do it's -9i
Divide the numerator by the denominator, and then multiply by 100 :)
