In the 3rd row where it says "3x(x-3)(x+3)", it should be "3x(x+3)(x+3)" and the solutions should be -3,-3,0
It is a system of weights and measures that evolved over time
and was once the de facto standard throughout much of the world. The best
definition of this system comes with the British Weights and Measures Act of
1824.
You probably know
that the English system of measurements holds few advantages. So why hasn't the
U.S. converted? The primary advantage to hanging on to the English system is
cost of conversion. For example, in 2009, NASA stated that the conversion of
the space shuttle program to SI would cost $370 million. This was a price tag
for which NASA simply did not have the funds. In another example, when Great
Britain began to process for metrification in the 1990s, the estimated cost for
changing all of its road signs was the equivalent of between $1.5 and $1.8
billion.
<span>The second advantage of continuing with the English
system is customary usage. For example, distances in football and baseball are
closely linked to feet and yards, and decades of records are kept in these
units. Cooking is another area where customary units in the U.S. are quarts,
cups, ounces, pounds, etc. Finally, our culture is filled with sayings, such
as, 'Give him an inch and he'll take a mile.' It just isn't the same to say,
'Give him 2.54 centimeters and he'll take 1.61 kilometers.'</span>
35% of x is 12....
0.35x = 12
x = 12 / 0.35
x = 34.29 <==
-2-2x≤2
To solve an inequality, it's just like an equation, first add 2 to both sides to get
-2x≤4
Divide both sides by -2to get
x≥-2
When you divide by a negative number, you flip the sign.
Your solution is x≥-2.
Hope this helped!
