Answer:

Step-by-step explanation:
So, our equation is:

In exponetial form, this looks like:

Now lets cube the 5:

Next, we can multiply the denominator on the right side by 5:

We need to now get x alone by adding 4 to both sides:

Finally, we divide by x's coefficent, 2, to get:

Step-by-step explanation:
repeating
1. Plug in 8 into x.
The equation will be 10(8)+5
2. Solve multiplication
80+5
3. The answer is 85! Hope this helped <3
2 x (L + W) = Perimeter
2(L + 16) = 80 Then divide both sides by 2
L + 16 = 40 Then subtract 16 from both sides
L = 24 feet
