Answer and explanation:
Given : Equations
1)
2)
To find : Tell whether the following equations are true or false. Then, explain your reasoning.
Solution :
Equation means when left hand side and right hand side of the equation is same.
1)
Take LHS,
Same term with opposite sign cancel each other or sum is zero,
Therefore, Yes, it is true as it satisfy definition of equation.
2)
Take LHS,
Same term with opposite sign cancel each other or sum is zero,
Therefore, Yes, it is true as it satisfy definition of equation.
A good place to start for this question is to define the properties of the geometric terms you are given.
Quadrilaterals have four straight sides.
Parallelograms are quadrilaterals that have two pairs of parallel sides. The opposite sides and opposite angles are congruent. Squares, rectangles, and rhombuses are examples of parallelograms.
Trapezoids are also quadrilaterals. They have only one pair of parallel sides.
So we're looking to see if there are any four-sided shapes that can be made with no parallel sides. The attached picture shows an example of a quadrilateral that is not a parallelogram and is not a trapezoid. Based on these properties of polygons, the correct answer is B.
