14) zeroes of the polynomial x^2+5x+6 are... Both positive
Both negative
One is positive and other is negative
None

both negative

Step-by-step explanation:

Descartes rule of signs tells us how many positive and negative real roots a polynomial has.

Given

f(x) = x² + 5x + 6 , with signs

+, +, + ← no change of signs, thus no positive zeros

f(- x) = (- x)² + 5(- x) + 6 = x² - 5x + 6 , with signs

+, -, + ← with 2 changes of signs. thus 2 negative zeros

B) Both Negative

Step-by-step explanation:

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.
