Simplify this expression
-2x + 3 -(5-6x)

4x-2

Step-by-step explanation:

−2x+3−(5−6x)

Distribute the Negative Sign:

=−2x+3+−1(5−6x)

=−2x+3+(−1)(5)+−1(−6x)

=−2x+3+−5+6x

Combine Like Terms:

=−2x+3+−5+6x

=(−2x+6x)+(3+−5)

=4x+−2

answer

step-by-step explanation:

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
