As you walk to physics class, you start out at a speed of 2 m/s, for a time of 120 seconds (you're really excited to get to class). Then you see your friend and slow down to a speed of 0.5m/s for 30 seconds.
You stop at your locker for 40 seconds (a speed of 0 m/s). You realize that you are about to be late so
you hurry to class at a speed of 1 m/s and get to class just as the bell rings (4 minutes after your trip
started). How far did you travel total?

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).

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
