3/4 because if you make it smaller you would get that
The "plus x minus two x" part basically means "minus x".
So, "six minux x equals five".
This means that six minus five is x. So, x is one!
Now, let's check this in the problem: replace x with 1. Six plus one minus two ones equals five? Yes, it does!
The answer is x=1.
A scalene triangle is a triangle that has 3 sides that are all different lengths.
Let these letters represent the problem:
a = 8.7
b = side 2
c = side 3
P = 54.6
To find the perimeter, we just need to add all the sides [ P = a + b + c ]
So, put what we have in the formula above.
54.6 = 8.7 + b + c
Best of Luck!
