Answer:
4
Step-by-step explanation:
First of all, subtract the rental fee. 357 - 85 = 272. Now, simply divide 272 by 68 to find the number of hours. 272 / 68 = 4.
(x+3)^4=(x+3)^2)^2=(x^2+6x+9)^2=x^4+36x^2+81+12x^3+108x
So I guess we are solving for x here :)
So here is my work...
a=2x+6xz
Basically I think it would be
a=6xz+2x
WAIT WAIT NO I'M WRONG FORGIVE ME!
It's x=a/2(1+3z)
In any rectangle, the area is given by the product of the width and the length.
Since in this case both dimensions are represented by the correspondent function, you need to multiply the function:
