The polynomial -2 x 2 + 500x represents the budget surplus of the town of Alphaville. Betaville's surplus is represented by x 2 - 100x + 10,000. If x represents the tax revenue in thousands from both towns, which expression represents the total surplus of both towns together?

a is the right answer

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

step-by-step explanation:

for volume, add base x height x width
