<span>9/25 and 28/45 are both rather large numbers as denominators, so you can expect your LCD to be a bit large as well. the way i find the LCD is by trial and error. i take the biggest of the denominators and multiply it by low numbers (1, 2, 3, etc.) until i find one that works for both.

45*1 = 45, which 25 doesn't go into evenly
45*2 = 90, which when divided by 25, results in 3.6, aka not a whole number
45*3 = 135, which divided by 25 results in 5.4
45*4 = 180, which divided by 25 results in 7.2
45*5 = 225, which is promising because it ends with "25", and results in 9

so your LCD, which is divisible by both 45 and 25, is 225.</span>

What is pi ? <br><br><br><br><br><br><br> ps. just trying this -.-
marysya [2.9K]
'Pi' ( π ) is the ratio of the circumference of a circle to its diameter.

The exact value of 'pi' can't be completely written with numbers, so whenever
we use 'pi', we always use an approximation.

Solve the quadratic equation using the quadratic formula: 3x^2 - 6x = 5
Fantom [35]

Answer:

x_{1} = 1+\frac{2\sqrt{6}}{3} \\\\x_{2} = 1-\frac{2\sqrt{6}}{3}

Step-by-step explanation:

3x^2 - 6x - 5=0

quadratic formula:

x=\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}

a=3     b=-6     c=-5

x=\frac{-(-6)+-\sqrt{(-6)^{2}-4*3*-5}}{2*3}

x=\frac{6+-\sqrt{36+60}}{6} \\\\x=\frac{6+-\sqrt{96}}{6} \\\\x=\frac{6+-\sqrt{2^{2}*2^{2}*2*3 }}{6} \\\\x=\frac{6+-4\sqrt{6}}{6} \\

so we have:

x_{1} = 1+\frac{2\sqrt{6}}{3} \\\\x_{2} = 1-\frac{2\sqrt{6}}{3}
