Ipromise brinliest this is very easy i just don't simplify the polynomial 3x2 + 5x – 5x2 – 4x + 5 – 2 a.)–8x2 – 9x + 3 b.)2x2 + x + 3 c.)–2x2– 9x + 3 d.)–2x2 + x + 3

Pick the description of a geometric object that best matches the real world object box for a deck of card

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).

Anyone know? will mark brainliest if correct
