Undefined (not a real number)

The square root of -256 would result in an imaginary number so by terms, it's "not real". The imaginary number would be 16i. 16x 16 =256, but since it's negative, it's √16 √16i.

Answer:

x = 7 and y = 5

Step-by-step explanation:

Given a parallelogram: opposite sides are =

5x - 5 = 3x + 9

2x - 5 = 9

2x = 14

x = 7

Given a parallelogram: the diagonals bisect each other.

5y = 7y - 10

-2y = -10

-2y/2 = -10/-2

y = 5

$\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2h$

put radius: 3 cm, height: 14 cm, π as 22/7

$\sf \rightarrow \dfrac{1}{3} *\dfrac{22}{7} * (3)^2(14)$

$\sf \rightarrow 132 \ cm^3$
