Answer:34
Step-by-step explanation:
First you multiply
-7•-3=21
Then you just add 9+4+21
9+4=13
21+13=34
Step-by-step explanation:
A(promotional sign)b
A=kb
4=21k
K=0. 1904
A=0. 2b
A=0. 2×7
A=1. 4
The nearest value of the mass is <span>3.27 grams
it s near 3.25
answer is c</span>
The 4C matrix is obtained when all elements of matrix C are multiplied by 4. It <span>has all the same elements as C, only multiplied by 4.
Let's analyze all matrices
A. Not all elements of A can be divided by 4 (3 can not be divided by 4, the solution is not a whole number).
B. All elements of matrix B can be divided by 4, which means that B is a $C matrix (there is a matrix C which multiplied by 4 gives the matrix B).
C. Not all elements of C can be divided by 4.
D. Not all elements of D can be divided by 4.
Solution: B
</span>
Pretty sure the first one is C
