Answer:
143 inches
Step-by-step explanation:
Let the triangle be
inches long.
Then the perimeter of the equilateral triangle will be
inches.
Let the length of the square also be
inches.
Then the perimeter is 
It was given that the perimeter of the equilateral triangle is 77 inches more than the perimeter of the square.
So we can write the relation


Also, the side of the triangle is 55 inches longer than the side of the square.
So we write
or 
We put equation (2) into equation (1) to get;

We expand the bracket to get;




Hence the triangle is 143 inches long.
First
we have to understand what the domain is. In a nutshell the domain is
the set of all x values that are represented in any given graph. In
this case we do not have a graph but we have the vertex. The x value
is 2, therefore: x
≥ 2.

The cheaper car service would be the second option, $10 upfront + $.05 per mile.
$4+$.70(12 miles)= $12.40
$10=$.05(12 miles)= $10.60
Hope this helps you! :D
