Answer: Original expression: 2x - 11 + 4x + 7 + 3(x-4)
Simplified: 9x - 16
Step-by-step explanation:
2x - 11 + 4x + 7 + 3(x-4) becomes 2x - 11 + 4x + 7 + 3x -12
Group like terms, then combine to simplify:
2x + 4x + 3x -11 + 7 - 12
2x + 4x + 3x = 9x
-11 -12 + 7 = =23+7= -16
Simplified expression: 9x - 16
Answer: 1

JUST KIDDING It’s A I did this in school before and got it correct :)
Answer:
The definition of a vector that you learn in linear algebra tells you everything you need to know about what a vector is in any setting. A vector is simply an element of a vector space, period. ... So, to say that a vector is a column of numbers, or a geometric object with magnitude and direction, is incorrect
Step-by-step explanation:
i hope this helps at all
So your equation would be x+3 times x+2 = 30
When you factor this out, you get x^2 + 5x + 6 = 30
Then you have to move the 30 over so you can set it equal to zero, so subtract 30 from both sides of the equal sign.
You now have X^2 + 5x -24 =0
Here you'd try to refactor, but unfortunately that doesn't work in this equation so you have to use the quadratic formula.
Look up the formula if you don't know it, it would be more confusing if I tried to type it out. Just keep in mind that for this equation, a=1 b=5 and c= -24.
