5 divides by 2 is 2.5 I hope that hekos
No
We know scale factor(k)=y/x
Calculate units as 1 and find k
For left side


Hence its not a copy
The answer is 9 cubic units
The answer is -7
2x-3(x+4)=-5
Multiply by -3
2x-3x-12=-5
Collect like terms
-x-12=-5
Move constant to the right to change its sign
-x=-5+12
Add
-x=7
Change the signs
x=-7
This is a case of direct variation.
