Answer:
4x - 2
Step-by-step explanation:
The perimeter of a shape is when you add up all the sides.
-So, you can write it as: 2x - 5 + 5 - x + 3x - 2.
-Group the terms together to get: 2x + 3x - x - 5 + 5 - 2
-Combine like terms to get: 4x - 2
Hope this helps! :)

Answer: B. An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles. dd
Step-by-step explanation:
An isosceles is a triangle that has two sides of equal length.
The isosceles theorem says that the angles opposite to the equal sides of a triangle are equal.
Thus, it also has two equal angles and one non equal angle. Thus, it does not have all congruent angles.
- The order of rotational symmetry of a figure is the number of times we rotate up to 360° the figure such that it looks exactly the same as the original figure.
When we rotate the isosceles triangle up to 360° , only 1 time it looks exactly same as in the beginning because at each rotation the order of angles changes.
Therefore, An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.
Answer:
The Answer Is A
Step-by-step explanation:
The Harappan civilisation is also called The Indus Valley Civilisation, this is because they built their cities along the Indus river. The reason behind this location can be found in the rest of the "Old World" civilisations like Mesopotamia or Egypt, the first built their cities along the rivers Tigris and Euphrates, the second along the Nil;: their respective civilisations thrived because the overflowing of their respective rivers produced favorable conditions for agriculture, their main support.
