x³ + 27 which can be written as x³ + 3³
It is in the form of a³ + b³ = ( a + b) ( a² - ab + b²)
so
x³ + 3³
= (x+ 3) (x² - x * 3 + 3²)
= ( x + 3 ) ( x² - 3x + 9)
Hope this helps you.
Yes it is because 18÷6 is 3 and 6×3=18
So the change in between terms is 5 so you would put 5x, then for the first term, which is 2, 5*1(x)(because it's first term) then the difference between 5-2(because it's the 2nd term) So you would plug 100 in for x so 5(100)-3=497. Hope this helped!
Answer: 9820
Step-by-step explanation:
Important physical properties that affect fertility include soil structure and texture. Structure is the amount of aggregation and pores in soil and texture is the proportion of clay and sand particles in soil. Both affect soil fertility by affecting water movement through soil, root penetration and water logging.
