Answer:

The third side has a length of 4x² + x - 16

Step-by-step explanation:

We can solve this by taking the value given for the perimeter, and subtracting the values of the other two sides:

3x² + 8x - 9 - (x² + 11x + 5) - (-2x² - 4x + 2)

= 3x² + 8x - 9 - x² - 11x - 5 + 2x² + 4x - 2

= (3 - 1 + 2)x² + (8 - 11 + 4)x - (9 + 5 + 2)

= 4x² + x - 16

ANSWER THREE VERY EASY QUESTIONS FOR 30 POINTS!!!
Alla [95]

Water in weathering rocks (like rain beating a Boulder/Mountain)


Sedimentary Rocks Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.


Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms!


Hope these are correct, good luck!
