Termites live in the tropical rainforest breaking down dead and decaying plant material. As they break down the plant material they release methane, a greenhouse gas. Annually, 1,000 termites release approximately 500 grams of methane. Given a density of 3.5 X 106 termites per hectare, what is the annual amount of methane released, in kilograms, by the termites inhabiting a 3,000 hectare of tropical rainforest.

Approximately 5,250,000 kg of methane would be released.

Step-by-step explanation:

Given: 1,000 termites release approximately 500 g of methane annually

           3.5 x termites per hectare

Thus, population of termites inhabiting 3,000 hectares = number of termites per hectare x 3,000

= 3.5 x x 3,000

= 10 500 000 000

= 1.05 x

Since 1,000 termites release 500 g of methane, then 10 500 000 000 termites would release:

x 500 g

= 5250000000 g

But 1000 g = 1 kg, so that;

 = 5250000 kg

Approximately, 5,250,000 kg of methane would be released by termites inhabiting 3,000 hectares of tropical rain forest.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
