Acompany wants to increase the 30 % peroxide content of its product by adding pure peroxide (100% peroxide). if x liters of pure peroxide are added to 600 liters of its 30 % solution, the concentration, c, of the new mixture is given by the formula below. how many liters of pure peroxide should be added to produce a new product that is 40 % peroxide? cequalsstartfraction x plus 0.3 (600 )over x plus 600 endfraction

  100 liters

Step-by-step explanation:

Fill in the desired concentration and solve for x.

100 liters of pure peroxide should be added to produce the desired product.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
