a seed company sells two grades of grass seed. And hundred pound bag of a mixture of rye and Bluegrass sells for $255, and a hundred pound bag of Bluegrass sales for $348. How many bags of each are sold in the week when the receipts for 18 bags are $5334?​

8 bags of rye & bluegrass mix

10 bags of bluegrass

Step-by-step explanation:

RB = bags of rye & bluegrass mix

B = bags of bluegrass

348B + 255RB = 5334

RB+B = 18     then RB = 18-B

substitute for RB

348B + 255(18-B) = 5334

348B + 4590 - 255B = 5334

reduce

93B = 744

B = 8

RB = 10

step-by-step explanation:

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
