Simply put, it says that the numbers can be added in any order, and you will still get the same answer. For example, if you are adding one and two together, thecommutative property<span> of addition says that you will get the same answer whether you are adding 1 + 2 or 2 + 1. This also works for more than two numbers.</span>

Answer:
x = 51/6 or 17/2
<u>Step-by-step explanation:</u>
9( x-3) = 3 (x + 8)
Distribute
9x - 27 = 3x + 24
Add 27 to both sides
9x = 3x + 51
Subtract 3x from both sides
6x = 51
Divide both sides by 6
x = 51/6 or 17/2
Percent is parts out of 100 so x%=x/100
38%=38/100=0.38
'of' means multiply 2,000,000 times 0.38=760000
Answer:
(-5+√5)/2 and (-5-√5)/2
Step-by-step explanation:
For a general quadratic equation of the form ax²+bx+c = 0
The value of x can be gotten using the general formula expressed as:
x = -b±√b²-4ac/2a
Now given the function
f(x) = x² + 5x + 5
We can get the zeros of the function in its radical form by simply applying the formula above.
From the equation given;
a = 1, b = 5 and c = 5
Substituting this values in the formula we have:
x = -5±√5²-4(1)(5)/2(1)
x = -5±√25-20/2
x = -5±√5/2
x = (-5+√5)/2 and (-5-√5)/2
The zeros of the function in its simplest radical form are
(-5+√5)/2 and (-5-√5)/2
