3.- Doña Queta cosechó zanahorias de su huerto, al contar las zanahorias se dio cuenta de que había cosechado el 230% de zanahorias con respecto del bimestre anterior, ¿Cuántas zanahorias cosechó?

2.3X

Step-by-step explanation:

Working out the number of carrots she harvested based on the data given:

Percentage of carrot harvested compared to previous 2 months = 230%

Let the number of carrots harvested over the previous 2 months = x

Therefore, the number of carrots harvested this month will be :

Percentage harvested * number harvested over previous 2 months

(230% * X)

230/100 * X

2.3X

Therefore, the number of carrot harvested is: 2.3X

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
