Question

What is the determinant of the image shown?
–74
–51
51
69

Answer 1

Answer: -61

Step-by-step explanation:A = -2{(-5× -1) - (3 × -2)} + -2{(-5×4) - (-2×1)} + -5{(4×3) - (-1×2)}

= -2{(5-(-6)} + -2{(-20 -(-2)} + -5{(12-(-2)}

= -2(5 + 6) + -2(-20+2) + -5(12+2)

= -2(11) + -2(-18) + -5(14)

= -22 + 36 -75

= -61
