No, because the number of rows of the first one has to equal the number of collumns in the 2nd matrix

none of them are equal (except 2=2 but same matrix0

Help please!!! Find the sum of the series show your work
AleksAgata [21]

Answer:

\sum_{i=1}^{12}(3i-1) = 222

Step-by-step explanation:

The given series is

\sum_{i=1}^{12}(3i-1)

The first term is

f(1) = 3 \times 1 - 1 = 2

The last term is

f(12) = 3 \times 12 - 1 = 35

To find the number of terms in the sequence, solve,

3i - 1 = 35

3i = 36 \\ i = 12

The sum of the first i-terms of an arithmetic sequence is:

S_i =  \frac{i}{2} (f(1) + f(2))

We substitute the values to get;

S_ {12}=  \frac{12}{2} (2+ 35)

S_ {12}=6(37)

S_ {12}= 222
