Which statement is NOT true? All squares are rhombuses.
All rhombuses are parallelograms.
The diagonals bisect each other in squares, rhombuses, and rectangles.
The diagonals are perpendicular in squares, rhombuses, and rectangles.

D

Step-by-step explanation:

Rectangles haven’t perpendicular diagonals

c

step-by-step explanation:

because of the levels

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
