(05.01 LC)A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square? A square with a side length of 6 units is shown. A diagonal is drawn with one section shaded inside the figure.

fraction 1 over 4 ⋅ 6 ⋅ 6
fraction 1 over 2 ⋅ 3 ⋅ 3
fraction 1 over 4 ⋅ 3 ⋅ 3
fraction 1 over 2 ⋅ 6 ⋅ 6

the answer is 4.8 units on e2020.

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).

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
