Answer:
x = 3
Step-by-step explanation:
First, simplify by subtracting 2x from 6x:
6x - 2x + 8 = 20
4x + 8 = 20
Then, solve for x:
4x + 8 = 20
4x = 12
x = 3
So, the answer is x = 3
Answer:
4x^2 -5x + 1 - 2x^2 - 9x + 6
2x^2 - 14x + 7
Step-by-step explanation:
Answer:
it depends
Step-by-step explanation:
The endpoints of the hypotenuse are insufficient to specify a right triangle. The perimeter can range from twice the distance between these points, about 18.868 units, to 1+√2 times the distance between these points, about 22.776 units.
___
In the attached figure, the colored numbers are the total length of the two legs of that color. The hypotenuse and its length are in black.
_____
The distance between two points is given by the formula ...
d = √((x2-x1)^2 +(y2 -y1)^2)
The perimeter will be the sum of the distances between pairs of points that define the vertices of the triangle. We need to know the third vertex to answer the question precisely.
Here are some examples.
1. see attachment
metric is all base 10.
1m=100cm=1000mm
measurements like kg and g and mg are sized by prefexes that are powers of 10
in imperial, we've got 12in=1ft and 3ft=1yard and other rediculous stuff like that
a comparison from tumblr is below
"to remember how many feet there are in a mile, u just gotta use 5 tomatoes
five to-mate-oes sounds like five, two, eight, 0 and there’s 5280 feet in a mile
To remember how many meters there are in a kilometre you just remember “1000” because the system of measurement in the rest of the world wasn’t invented by a drunk mathematician rolling dice."
2. metric has a separate measurement for Mass and force (kg and Newton) while English has. lbs being used for both (technically mass is slugs and force is lbs but who uses slugs to find mass?
I conclude with this exerpt from Josh Bazell's Wild Thing
“In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘***********,’ because you can’t directly relate any of those quantities.”
