What of the following is not a characteristic of all parallelograms diagonals bisect each other be opposite angles are congruent c diagonals are angle bisectors deep is the sides are congruent

So  , the correct option is the diagonals are angle bisectors which is not a characteristic of all parallelograms.

Step-by-step explanation:

The properties of parallelograms are as follows:

i) the diagonals of a parallelogram bisect each other

ii) opposite sides are congruent

iii) opposite angles are congruent

iv) consecutive angles are supplementary

v) the diagonals are angle bisectors only if all the sides of the parallelogram are equal.

So  , the correct option is the diagonals are angle bisectors which is not a characteristic of all parallelograms.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
