If a sprinkler waters 1/12 of a lawn in 1/4 hour, how much time will it take to water the entire lawn?

3 hours

Step-by-step explanation:

1/12 = 1/4 of an hour

1 hour = 4/12

2 hours = 8/12

3 hours = 12/12

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
