You add/subtract complex numbers simply by adding/subtracting real parts and imaginary parts.
So, the real part of this sum is the sum of the real parts:

And the imaginary part of this sum is the sum of the imaginary parts:

So, you have

the Given data
*The given point is (-1, -5)
*The given scale factor is 5
The image of -1 - 5 after dilation by a scale factor of 5 centered at the origin is given as

Thus, the image after dilation by a scale factor of 5 centered at origin is (-5, -25)
Answer:
3
Step-by-step explanation:
Number of scarves Tail could make = 4 7/8 ÷ 1 5/8
= 39/8 ÷ 13/8
Answer:
B : Length is 12, Width is 9
D: Area is 108
Step-by-step explanation:
Finding x:
Since the Perimeter is 42, subtract 14 from 42 to get 28. Then divide that by 4 to get 7. x = 7. Since x = 7 then 7 + 5 = 12. So the length is 12.
Figuring out the width:
When we find the perimeter we add all the sides, so 12 + 12 = 24 and 42 - 24 = 18. Divide 18 by 2 to get 9 and then add 12 + 12 + 9 + 9 just to check your answer
Since the you know the legnht and width, you now have to multiply them to fine the area. 12 x 9 = 108
Step-by-step explanation:
12 pages=10 minutes
1 page=12:10=1.2 minutes
168 pages= 1.2×168= 201.6 minutes
so 3.36 hours
