You need a 45% alcohol solution. On hand, you have a 65 mL of a 30% alcohol mixture. You also have 50% alcohol mixture. How much of the 50% mixture will you need to add to obtain the desired solution?

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the answer is 11.2 (i know i’m late)

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).
