ziro4ka [17]4 years ago
6 0

Answer:

G (4 , -4)

Area CDEF : 176

Step-by-step explanation:

CD ⊥ x axis

FE ⊥ x axis

Point G (x , y)     x = 4 and y = -4

G (4 , -4)

CD = 5 + 4 = 9

FE = 7 + 6 = 13

DG = 12 + 4 = 16

Area CDEF = (Cd + FE) x DG / 2 = (9 + 13) x 16 /2 = 176

Examples of singular and non-singular matrix.​
finlep [7]

Answer:

Step-by-step explanation: For example, if we have matrix A whose all elements in the first column are zero. Then, by one of the property of determinants, we can say that its determinant is equal to zero. Hence, A would be called as singular matrix. Note that singular matrices are non-invertible (their inverse does not exist).
