-9 + 279 = 270.
different signs (negative vs positive) subtract, keep the sign of the highest number.

-9 - 279 = -288.
same signs add and keep

-9 • 279 = -2,511. positives and negatives always equal negatives.

Figure ABCD is a parallelogram. What is the value of n?

Zigmanuir [339]

Answer

Find out the what is the value of n.

To prove

By using the parallelogram property .

In parallelogram opposite angels are congruent .

As shown in the figure .

∠B = ∠ D

As given

∠B = (2n + 32)°

∠D = (4n - 2)°

(2n + 32) = (4n - 2)

solving the above

4n -2n = 32 +2

2n = 34

$n = \frac{34}{2}$

n = 17

Therefore the value of n is 17 .
