Here a = 3, b = 5, c = 7, d = 2.
So,
(ad - bc) = (3 x 2) - (5 x 7) = 6 - 35 = - 29.
So,
(ad - bc) = (3 x 2) - (5 x 7) = 6 - 35 = - 29.

Determinant formula = |ad-bc|.
Here a=3, b=5, c=7, d=2.
(3*2)-(7*5) = -29.
Answer = -29.
Here a=3, b=5, c=7, d=2.
(3*2)-(7*5) = -29.
Answer = -29.

|3 5|
|7 2| = (3*2)-(7*5) = (6-35) = -29
Therefore, the answer is -29.
|7 2| = (3*2)-(7*5) = (6-35) = -29
Therefore, the answer is -29.
