Answer:
102
Step-by-step explanation:
The least common multiple of 6 and 17
For us to determine the L.C.M of 6 and 17,
First find the prime factors of 6 and 17
Prime Factor of 6
6 = 2 × 3
Prime factor of 17
17 = 1 × 17
Secondly;
Multiply all the factors together to find the L.C.M:
L.C.M = 1 × 2 × 3 × 17
L.C.M = 102

Answer:
B. 8
Step-by-step explanation:
The question lacks the required diagram. Find the diagram in the attachment.
Before we can find d21, d22 and d23, we need to get the matrix D first as shown in the attached solution.
On comparison as shown in the attachment, d21 = 11, d22 = -10 and d23 = 7
Note that d21 refers to element in the second row and first column of the matrix
d22 is the element in the second row and second column of the matrix
d23 is the element in the second row and third column of the matrix
d21+d22+d23 = 11-10+7
d21+d22+d23 = 8
The second option is correct.
