The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A it is true.
The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A. A determinant of an n×n matrix can be defined as a sum of multiples of determinants of (n−1)×(n−1) sub matrices.
This is done by deleting the row and column which the elements belong and then finding the determinant by considering the remaining elements. Then find the co factor of the elements. It is done by multiplying the minor of the element with -1i+j. If Mij is the minor, then co factor,
+
.
Each element in a square matrix has its own minor. The minor is the value of the determinant of the matrix that results from crossing out the row and column of the element .

- 1. B. Step 2 has an error. Instead of adding 3x and 30x, Suzie has subtracted 3x from 30x. And also, she has not added -4 and -40. The correct step will be 33x - 44.
- 2. A. 11(3x - 4).The next step will be 11(3x - 4).

Answer:
Ok
Step-by-step explanation:
Answer:
No; the corresponding angles are not congruent
Step-by-step explanation:
Two figures are similar when they have proportional corresponding sides and congruent corresponding angles.
Trapezoid ABCD has two right angles B and C, obtuse angle A of measure 137° and acute angle D of measure 43°.
Trapezoid EHGF has two right angles G and F, obtuse angle E of measure 136° and acute angle H of measure 44°.
Since obtuse angles and acute angles are not congruent, trapezoids ABCD and EHGF are not similar
