A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon. One side is 5-2x
The other one is -4x + 9
One side is blank
It's a triangle

Step-by-step explanation:

So if it is a triangle it is a equilateral triangle.

if all the sides equal eachother, we know to find x.

5-2x=-4x+9

+4x

5+2x=9

-5    -5

2x=4

/2

x=2

So if a triangle has three sides, we multiply 2 x 3 or (x) times the number of sides.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
