Which of the following expressions is equivalent to 9m? m – 9 9 + m (9)( m)
Lena [83]

Answer:

(9)(m)

Step-by-step explanation:

We can obtain the right answer to question as follow:

m – 9

We can not carryout the operation because m and 9 has nothing in common.

9 + m

We can not carry out the operation because 9 and m has nothing in common.

(9)(m)

Thus, (9)(m) can be written as

(9)(m) = 9 × m

We can carryout the operation since 9 can multiply the coefficient of m i.e 1 as shown below:

9 × m = 9 × 1m = 9m

Thus,

(9)(m) = 9m

From the above illustrations, we can see that (9)(m) is equivalent to 9m
