Question

Evaluate ad-bc for the given values of the variable. a=-3,b=-5,c=2,d=9

Answer 1

The given epression is

ad - bc

We would substitute a = - 3, b = 5, c = 2, d = 9 into the above expression. It becomes

$\begin{gathered} (-\text{ 3}\times9)\text{ - (5}\times2) \\ -27\text{ - 10 = - 37} \end{gathered}$

The solution is - 37
