I don’t know how to solve its very hard sorry I can’t even solve it ;(
=0 is the answer to the equation
Answer:
5x + 2y + z
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of all the sides of the polygon. This polygons has 8 sides. Their lengths are:
x, x, x, x, x, y, y, z
The perimeter of the polygon is the sum of the lengths shown above.
perimeter = x + x + x + x + x + y + y + z
The expression above can be simplified by combining like terms.
perimeter = 5x + 2y + z
The answer to this question is 17.5. Because i divided 20 by 8 and got 2.5 and times it by 7.
17.5
