For the base of the shape all you need to do is multiply 25x25=625ft²
then for the 4 sides you need to multiply 25x32=800ft²
and because there are 4 sides you multiply 800x4=3200
so now you add 3200 with 625 (3825) and there's your area
I think the rate is decreasing from:
(-infinity, ln9/3)
To solve an algebraic equation, we need to get x by itself. We can start to do that by multiplying each side of the equation by 62 (to remove the denominator of x).
x + 89(62) = 92 * 62
Simplify
x = 92 * 62 - 89 * 62
Now we can factor out 62
x = 62 (92 - 89)
Now we can simplify the parenthesis
x = 62 * 3
x = 186
