Asemicircular section of a running track consists of eight lanes that are 1.2m wide. the innermost line of the first lane has a total length of 100m. how much further will someone in lane 8 run around the curve from the start line to the finish line?

correct answer:

b.(19,-2)

yes

step-by-step explanation:

yes

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).
