Which of the following statements is never true? a. a parallelogram is a quadrilateral. b. a trapezoid is a parallelogram. c. a square is a rhombus. d. a kite is a quadrilateral.

B.A trapezoid is a parallelogram.

Step-by-step explanation:

We know that "a quadrilateral has four sides."

A parallelogram is a kind of quadrilateral with opposite sides are parallel.

So statement A is always true.

A trapezoid is a kind of quadrilateral with two parallel and two non-parallel sides, thus it never be parallelogram, thus statement B is never true.

A square is a kind of rhombus having all interior angle as right angle.

So statement C. is always true.

A kite is a kind of quadrilateral, whose two adjacent sides have equal length and its diagonal s are perpendicular to each other.

So statement D is always true.

c is the answer

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
