you_die!!! Super_Chihuahua We're learning that in math right now too...And we were in a portable wing, but it was really cold...I could almost see my breath! We're supposed to show all our work... But I don't show any of it... We do our math work in the main building, but we are learning how to do ratio problems. I am so far ahead of that that I just skip ahead and read some tougher problems near the back of the book. Then I get better problems like: 26P14 and stuff like that.
We just hardly do math at all...
Instead most of us sit there and drool. And then we get worksheets. We almost never work out of the book, heh! |

I almost never get worksheets, and we almost always work out of the book! xd
And to explain the equation that I just posted, you need to do 26! and 14!, and then put 26!/14! and you have the answer for P. |

you_die!!! my dog ate my sanity Seriously ... it's easy ... like ... Expand and Simplify: 2(5x + 4)(3x - 7) + (6x + 5y)(x - 3y) ... but now I feel the need to take excessive amounts of aspirin ... The answer for the simplify part is: 2(8x-3)+(7x+2y), or 2(15x-3+2y). The expand part I don't really understand too well.
Actually, you'd need to multiply the 2 into the first bracketed thing before doing the adding
The expand part is "FOIL"-ing the bracketed numbers
2( 15x^2-23x-28 ) +( 6x^2-13xy-15y^2 )
Then multiplying the 2 into the first bracketed trinomial (at which point you can get rid of the brackets)
30x^2-46x-56+6x^2-13xy-15y^2
The simplify is collecting like terms
Answer= 36x^2-46x-56-13xy-15y^2
(the blah blah ^2 means whatever-it-is squared) |
