The population of a country has been increasing for several decades. In 1990, the population was about 271 million people. In 2014, the population was about 344 million people. Determine the percent increase in the country's population during this time period.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

no idea

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

-1/3(x+1)^5

i’m pretty sure this is correct
