Faith mixes 14 liters of 12% acid solution with a 30% acid solution, which results in an 18% acid solution. how many liters of 30% solution did she use? a. 4.7 liters b. 21 liters c. 12 liters d. 7 liters. will give brainiest!

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

Answer! if you don’t mind, can you explain

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no
