Answer:

x = -5/7 or x = 2

Step-by-step explanation:

7x² - 9x - 10 = 0

Factor the left side of the equation.

(7x + 5) (x - 2) = 0

Set the factors equal to 0.

7x + 5 =0

7x = -5

x = -5/7

x - 2 = 0

x = 2

tatyana61 [14]

Answer:

<h2>4178kids</h2>

Step-by-step explanation:

Area of the basket ball court = Length * Breadth (since it is rectangular in nature)

Area of the basket ball court = 94 feet * 50 feet

Area of the basket ball court = 4700ft²

Area of the space covered by 8 kids = 3ft * 3ft = 9ft²

To know the number of kids that would fit the entire floor, we will use the expression;

Number of kids in the floor = 8*Area of the basket ball court /Area of the space covered by 8 kids = 8*4700/9

= 8*4700/9

= 8*522.22

≈ 4,178 kids

<em>Hence approximately 4,178 kids can fit side by side  over the entire floor</em>
