Distinguish between regional and contact metamorphism. a. Contact metamorphism occurs when chemically active fluids flow through

a large region of preexisting rock; regional metamorphism occurs when large quantities of rock are subjected to high heat and pressure during mountain building. b. Regional metamorphism occurs when magma intrudes existing rock and heats it enough to cause metamorphic changes; contact metamorphism occurs when large quantities of rock are subjected to high heat and pressure during mountain building. c. Contact metamorphism occurs when magma intrudes existing rock and heats it enough to cause metamorphic changes; regional metamorphism occurs when large quantities of rock are subjected to high heat and pressure during mountain building. d. Regional metamorphism and contact metamorphism both occur when quantities of rock are subjected to high heat and pressure during mountain building, but regional metamorphism affects over a greater area. e. Regional metamorphism occurs when chemically active fluids flow through a large region of preexisting rock; contact metamorphism occurs when magma intrudes existing rock and heats it enough to cause metamorphic changes.

4x+28=2x+24+2x+2 slove for x
Alinara [238K]

The answer you are looking for is x = 0 (or undefined)

To solve for x, you would first combine all the like terms on the right side. To do so, add 2x and 2x to get 4x and add 24 and 2 together to get 26. This will give you 4x + 28 = 4x + 26, which you can now solve.

To find x, you would get the x by itself. However, in doing so you would get 0 or 0x. This is because you would subtract 4x on both sides to cancel out the 4x on the right, but in this case, it will also cancel out the 4x on the left. Thus meaning the answer is 0 or undefined.

I hope this helps!

Que características (naturales,sociales y económica) influyen para que algunos países tengan muy alto porcentaje de población ur
lbvjy [14]

Answer:

Por regla general, los países que tienen una alta proporción de población urbana son países que tienen una proporción de la actividad económica muy sesgada hacia la industria o los servicios, y como éstos dos sectores económicos tienden a ser más productivos que el sector primario (que se compone de agricultura, ganadería y minería), los países urbanizados también tienden a ser los más desarrollados.

Por ejemplo, en Alemania, un país desarrollado e industrializado, el porcentaje de población urbana es de más del 70%, mientras que en Burkina Faso, un país muy rural, y uno de los más pobres del mundo, el porcentaje de población urbana es de apenas el 30%.
