What is always true of the diagonals of a parallelogram?

The diagonals of parallelogram bisect each other.

Step-by-step explanation:

Consider the provided statement.

The parallelogram has few properties.

1: The opposite side of parallelogram are parallel by the definition of parallelogram.

2: The opposite sides and angles of a parallelogram are congruent.

3: The consecutive angles of a parallelogram are supplementary.

4: The diagonals of parallelogram bisect each other.

From the above properties of a parallelogram we can say that:

The diagonals of parallelogram bisect each other.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
