A city holds an election for Mayor every 10 years, an election for Treasurer every 4 years, and an election for Attorney General every 8 years. It held elections for all three positions this year. At least how many years will it be before the election for all three positions happens in the same year again?​

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
