A football team has a net yardage of −28 1/3 yards on a series of plays. The team needs a net yardage of 30 yards to get a first down. How many yards do they have to get on their next play to get a first down?

58 1/3 yards

Step-by-step explanation:

From the question, we are informed that a football team has a net yardage of −28 1/3 yards on a series of plays and that the team needs a net yardage of 30 yards to get a first down.

The number of yards that they have to get on their next play to get a first down would be calculated as:

= 30 - -28 1/3

Note that minus × minus = plus

= 30 + 28 1/3

= 58 1/3 yards

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
