The lengths of the sides of a triangular sign are x inches, (4x - 5) inches, and (7x+8) inches. What is the perimeter of the sign? The perimeter of the sign is in.
(Simplify your answer Do not factor)

The perimeter of triangular sign is 12x+3

Step-by-step explanation:

Length of side1 of triangle = x inches

Length of side2 of triangle = 4x-5 inches

Length of side3 of triangle = 7x+8 inches

We need to find perimeter of triangular sign.

The formula used is:

Now, finding perimeter of triangular sign:

The perimeter of triangular sign is 12x+3

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
