A merchant offers a large group of items at 18% off. Later, the merchant takes 10% off these sales prices and claims that the final price of these items is 86 off the original price. What is the total percent discount?
answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°
so ac is the half of 24=12ft,and from the pythagorean theorem we find ba
so bac is 12+12√3=12(1+√3)ft
the correct answer option is (2x-3)(2x+3).
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 [tex]4x^2-0x-9[/tex] is (2x-3)(2x+3).
