Evaluate the expression  e^ln^ 12.

Step-by-step explanation:

I suppose your intended expression is;

The exponential function, e, and the natural logarithm function, ln, are inverses of each other;

Therefore, our expression becomes;

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
