On a number line, the surface of a river is marked at -220 feet and the top of a building is marked at +19 feet, where 0 represents sea level. What do -220 and +19 represent? A) 220 feet below sea level and 19 feet above sea level.

B) 220 feet above sea level and 19 feet below sea level.

C) 220 feet below sea level and 19 feet above 220.

D) 220 feet above sea level and 19 feet below 220.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
