i need the work plz

-136

Step-by-step explanation:

We have to find the determinant of the following matrix:

We can find the determinant by expanding via 1st column. i.e. by taking each element of 1st column and multiplying it by its co-factor matrix as shown below:

det

=

The notation det() stands for determinant of the matrix.

Therefore, the determinant of the given matrix is -136

mxb67

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
