Answer:
Properties of rhombus
. all the properties of a parallelogram( apply the ones that matter hair are parallel sides opposite angles congruent and consecutive angles are supplementary)
. all sides are congruent by definition
. the diagonals bisect the angles
. the diagonals are perpendicular bisectors of each other
Properties of rectangle
. all the properties of parallelogram apply (the ones that matter hair are parallel sides, opposite sides are congruent, and diagonals bisect each other)
. all angles are right angles by definition
. the diagonals are congruent
Properties of square
. all the properties of a rhombus apply( the ones that matter have a parallel sides diagonals are perpendicular bisector of each other and diagonals bisect the angles)
. All the properties of rectangle apply (the only one that matter where is diagonals are congruent)
. All angles are right angles by definition
Hope it will help you
Step-by-step explanation:
(6 - 8x) + (-6 + 9x) = (6 - 8x) + (9x + (-6)) = (6 - 8x) + (9x - 6)
Commutative property: a + b = b + a
100 + x-4 +3x =180
x = 21
hope it help
Following expressions will have negative product

Following expressions will have positive product

Further explanation:
We will see at each expression one by one
First expression is:

In the given expression one term is positive and one term is negative. The product of negative and positive terms is negative.
Second Expression is:

Both terms are negative and the product of two negative terms is positive.
Third Expression is:

The expression has one positive and one negative term so the product will be negative
Fourth Expression is:

Both terms are positive so the product will also be positive
