Answer:

у = x² + 7x - 30

Step-by-step explanation:

x₁ = 3 and x₂ = -10

Use the formula    (x - x₁)(x - x₂) = 0

(x - 3)(x - (-10)) = 0

(x - 3)(x + 10) = 0

x² + 10x - 3x - 30 = 0

x² + 7x - 30 = 0

Dmitriy789 [7]

Answer

Find out the how many games did the teams lose .

To prove

Formula

Percentage = \frac{Part\ value\times 100}{Total\ values}

As given

Salem High School's winter sports teams WON 72% of their games last season.

If the teams played 50 games .

Percentage = 72%

Total value = 50

Put in the formula

72 = \frac{Number\ of\ games\ win\times 100}{50}

Number\ of\ games\ win = \frac{72\times 50}{100}

Number of games win = 36

Number of  games teams loses = Total number of games - number of games win

                                                          = 50 - 36

                                                          = 14

Therefore the number of games  team loses are 14 .
