you must factorize it as a difference of squares

a^2-b^2 = (a-b)(a+b),

9b^2-25 = (3b)^{2-(5)^2= (3b-5)(3b+5)

If one inch represents 15 feet, then:

2 inches represent:
2 * 15 = 30 feet

1 2/3 inches represent:
1 2/3 * 15 =
= 5/3 * 15 =
= 75/3 =
= 25 feet

So the real area of the court is 30 * 25 = 750 square feet.

Find the distance between the given points (2,8) and (7,7)
Ray Of Light [21]

Answer:

d=\sqrt{26}\approx5.0990

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula.

The distance formula is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:

d=\sqrt{(7-2)^2+(7-8)^2}

Simplify:

d=\sqrt{5^2+(-1)^2}

Square:

d=\sqrt{25+1}

Add:

d=\sqrt{26}\approx5.0990

And that's our answer :)
