The value of y is 4.
4+4 is 8.
The sequence is 8, 6, 4. The common difference is -2.
Parallel sides mean that they are always the same distance from each other and will never touch. Knowing that, let's think of the shapes.
Rectangle: Yes, opposite sides are parallel. The two opposite sides of a rectangle will never touch.
Rhombus: Think of it as a diamond. You can still view it as a rectangle that has the top shifted over a bit. Therefore, yes, opposite sides are parallel because they will never touch.
Square: Is basically the same as the rectangle. Therefore, the answer is yes, opposite sides of squares are parallel.
Parallelogram: The definition of a parallelogram, like in its name, is a four-sided figure with opposite sides parallel. Therefore, yes, parallelograms have opposites sides that are parallel.
Therefore, the answer is all four of them.
1.50 times 2 is 3 so you would have to use the tag twice for it to be equal to not using it
The answer is C hope this HELPED!!!!!!!
