It has 3 zeros, because its a polynomial of degree 3.
Answer(a):
Order of matrix A = 3x3 {because number of rows=3, number of columns=3}
Order of matrix B = 3x3
Order of matrix C = 1x3
3A will be of order 3x3 because multiply by scalar doesn't change the order. Which is same as the order of matrix B.
So 3A+B is possible.
We simply multiply all elements of A with 3 and add them with corresponding elements of B.

Answer(b):
2B will be of order 3x3 because multiply by scalar doesn't change the order. Which is NOT same as the order of matrix C.
So 2B+C is NOT possible.
Answer(c):
CA is possible only if
number of columns of C = number of columns of A
3=3
which is true hence CA is possible.

10% off means the jeans will sell for 90% of the original price ( 100% - 10% = 90%)
Multiply the original price by 90%
65.00 x 0.90 = 58.50
He will pay $58.50

Answer:
sequence is not arithmetic
Step-by-step explanation:
Given:
8,5, 3, 2,
above is not arithmetic sequence
As there is constant difference in consecutive terms in a an arithmetic sequence given by:
d=an- an-1
where
d is common difference
an=nth term
an-1=nth - 1 term
Given sequence
8,5, 3, 2,
d=5-8 = -3
d-3-5=-2
as the difference is not common above sequence is not arithmetic!
