Calculate the perimeter of an equilateral triangle of side 3cm

P=9cm

Step-by-step explanation:

When the triangle is equilateral, it means that all sides are equal. In this case, all three sides are 3cm.

The equation to find the perimeter for a triangle is just to add all sides.

This becomes:

3+3+3=9.

So, in conclusion, the perimeter of this equilateral triangle is 9cm.

Hope this helps, and have a nice day:)

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
