Answer:
−3a+38
Step-by-step explanation:
i simplified the expression
Step-by-step explanation:
The answer would be 13.546
you would do 162.56 divided by 12.
So before we can find the perimeter, we need to find the hypotenuse. Since this is a right triangle, we can use the pythagorean theorem. The equation for that is
, in which a and b are the legs of the triangle and c is the hypotenuse.
With this info, we can form our equation: 
Firstly, solve the exponents: 
Next, combine everything on the left side: 
Next, square root both sides, and your hypotenuse will be 15 = c.
Now that we have all the triangle side lengths, just add everything up: 
In short, the perimeter is 36 inches.
