What are the solution(s) to the quadratic equation 9x2 = 4?
Oksanka [162]

we have

9x^{2}=4

Divide both sides by 9

9x^{2}/9=4/9

x^{2}=4/9

Square root both sides

x=(+/-)\sqrt{\frac{4}{9}}

x=(+/-)\frac{2}{3}

so

the solutions are

x1=\frac{2}{3}

x2=-\frac{2}{3}

therefore

<u>the answer is the option</u>

x = 2/3 and x = -2/3

Answer: A

Step-by-step explanation:

The area of the square is 10^2 = 100.

The area of the circle is (pi)(5^2) = 25pi.

So, the area of the region in the square but not in the circle is 100 - 25pi.

Thus, the desired probability is (100-25pi)/100, which is about 21.5%
