(-2x^2). (-5x^2)+(-2x^2)(4x^3)
10x^4-8x^5
An equation is:
2(x+3)-7=9
Distribute the 2
2(x)+2(3) -7=9
2x+6-7=9
Combine like terms
2x-1=9
Add one to both sides
2x-1+1=9+1
2x=10
Divide both sides by two to isolate the variable.
2x/2=10/2
x=m
The answer is b because if you look there is no Direct variation
