Answer:
Weathering
Step-by-step explanation:
Weathering is the physical and chemical breakdown of rock at the earth's surface. The physical breakdown of rock involves breaking rock down into smaller pieces through mechanical weathering processes. These processes include abrasion, frost wedging, pressure release (unloading), and organic activity.
Answer:
x = -3, -6.
Step-by-step explanation:
3x2 + 27x + 54 = 0
Divide through by 3:
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
x = -3, -6.
None of them are equivalent because
= 3(-2)+7
= -6 +7
= 1
Therefore x(x+1)≤0, and if two numbers multiply to a negative number, one of them has to be negative and the other has to be positive. In this case, because x+1>x, x≤0, and x+1≥0
Therefore -1≤x≤0, and x can take up the value of any real number in the interval [-1,0]
