Given a rhombus, a square, and a rectangle, what must be true of all three quadrilaterals?

a.

the diagonals are congruent.

b.

the diagonals bisect each other.

c.

the diagonals are perpendicular.

d.

each of the diagonals bisects both angles.

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
