Pythagorean theorem HELP PLZ i am doing other ones can you plz do this one

it is the 1st one.

Step-by-step explanation:

The pythagorean theorem is , a and b standing for the two legs and c stands for the hypotenuse (slanted line connecting the two). Since and , we add 4 and 9 to get 13. Since 3 is already squared, we can look at it like . Therefore, the first answer, "2,3,", is correct. Hope this helped!! :]

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

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.
