–4
30
60

Therefore the correct option is third

i.e determinant A i.e |A| = 30

Step-by-step explanation:

Given:

To Find:

determinant A i.e |A| = ?

Solution:

Determinant A is given as

Therefore the correct option is third one i.e determinant A i.e |A| = 30

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
