Answer:

Option B.

Step-by-step explanation:

We have the following polynomial: -10x^2+12x-9=0

Multiplying by -1:

10x^2-12x+9=0

Using the quadratic formula, we find that the roots are:

0.6 ± 3√(6)/10i

Therefore, the correct answer is B.

The length of a tennis court is 10 feet shorter than 3 times its width x express and the perimeter of the tennis court in terms
Norma-Jean [14]

First, let's define our variables.


Let's call our width X(given)

and our length, since it's 10 shorter than 3 times the width, we can call our length:

3x-10

So, the perimeter of a rectange is equal to 2 times the length + 2 times the width.


So, when we plug our values in, we get

2(3x-10)+2x\\6x-20+2x\\8x-20

The perimeter is 8x-20
