It takes an express train 30 minutes to travel 45 miles at that same rate of speed how many miles does the train travel in 12 minutes

Well if you divide 30 by 10 then multiply by 4 you get 12 minutes.

Do the same for 45,

45 divided by 10 = 4.5 then multiply by 4 =  18

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
