Step-by-step explanation:
27^x = 9^(x - 4)
3^3x = 3^2(x - 4)
3x = 2(x - 4)
3x = 2x - 8
3x - 2x = -8
x = -8
Is the last part y to the 4th power? If it is I like to write it y^4 to avoid confusion.
So anyway the coefficient is the number accompanying the variable so the answer is C. 2
Hope this helps.
Multiply the length of the model by 10
