9x^2 + 18x + 9 = 5
9(x^2 + 2x +1) - 5 = 0
x^2 + 2x - 4 = 0
Then use the quadratic formula.
The answer
<span>the amount of gold per cubic meter can be found by the ratio
0.78 g /1 </span><span>.5 cubic meters = 0.52 g / cubic meter,
proof
it was said </span><span>the amount of gold per cubic meter (Density)</span>
Using the distributiver property which is
a(b+c)=ab+ac therefor
2(x-2)=2(x)+(2)(-2)
multiply
2x+-4
2x-4
2x-4=2x-2?
false
the answer is no
can be simplified to
, which is an irrational number around 1.732
I hope this helps!
