Which of the following statements are always true? select all that apply. quadrilaterals are squares. parallelograms are trapezoids. rectangles are squares rhombuses are quadrilaterals squares are parallelograms

Quadrilaterals are squares - True. Any polygon that has 4 sides is called a quadrilateral. The examples are - parallelograms, squares, rectangles, and trapezoids.

Parallelograms are trapezoids - False. A trapezoid has only 2 sides parallel but a parallelogram has 2 pairs of parallel sides.

Rectangles are squares -  False. For a rectangle to be a square, its all 4 sides must have the same length.

Rhombuses are quadrilaterals - True. A quadrilateral is a square if it has four congruent sides and four right angles. And a square is both a rhombus and a rectangle.

Squares are parallelograms - True. The squares and rhombuses have opposite sides with same length and the opposite sides are parallel to each other just like parallelograms.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
