However you are answering, the way you wrote it should be fine. I'm just going to check to see that it is correct.

-2[3x - (b + 2x) + (x - 3b)] Remove the inside brackets ()

-2[3x - b - 2x + x - 3b] Collect like terms inside the square brackets.

-2[ 3x - 2x + x - b - 3b]

-2[2x - 4b] Now remove the square brackets.

-4x + 8b So your answer and mine agree.

Just write it as you see it.

OlgaM077 [116]

Answer:

The answer to your question is 0.057 ha

Step-by-step explanation:

Data

Kilocalories needed for a person per day = 2450

Kilocalories produced per hectare = 15737000

Process

1.- Calculate the number of kcal needed per a person for a year

                     2450 kcal ----------------- 1 day

                         x            ----------------- 365 days

                              x = (365 x 2450) / 1

                             x = 894250 kcal

2.- Calculate the amount of land needed

                    15737000 kcal ------------- 1 ha

                        894250 kcal ------------  x

                          x = (894250 x 1) / 15737000

                          x = 0.057 ha
