Which statements are true? choose all answers that are correct. a. all quadrilaterals can be classified as either parallelograms or trapezoids. b. all rhombuses are parallelograms. c. some trapezoids are parallelograms. d. some parallelograms are squares.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
