hey....algebra 1 help here?

(FYI, on question 1, if x+3 is in the denominator, you should write it as x/(x+3), otherwise it is 1+3.  I have assumed that all of your denominators are written incorrectly.)\n\n1. cross multiply (x=6)\n2. set denominator = zero  (x=5)\n3. set denominator = zero  (x = -2)\n4. set it up like a long division or factor  (x+6)\n5. if you divide area by width you get length (L = 2x-3)\n6. multiply everything by x and solve. (x = 3)\n7. multiply everything by x and solve (x = 8)\n8. multiply everything by x^2+x and solve (x = 1 and 2)\n9. develop and equation where y = a*x  (y = (1/3)*x)\n\nFYI, the guy below me is wrong whenever his answer disagrees with mine.  For example, look at number 9. y=3*x would mean that if x = 12 then y = 36.  This is wrong!  My answers are correct.

OK,as the first one is already done,I am doing the rest for you\n4(2x-6)=x+2 =>8x-24=x+2  =>8x-x=2+24  =>7x=26  =>x=26/3=8 2/3  (3) 2(x+5)+1=3(x-1)+4   =>2x+10+1=3x-3+4 =>2x-3x=-3+4-10-1  => -x=-4  =>x=1  (5)x+6=4(4x-1)   =>x+6=16x-4  =>x-16x=-4-6  => -15x=-10  =>x=-10/-15=2/3 [after reducing]

If you can't get an answer here, try asking your Algebra teacher for extra help after school tomorrow.  It's sure to add to your grade that you asked for the help.

I'm not sure of your notation in the second one... did you mean x² + x?  I'll assume so.\n\nFirst solve the first equation:\n3x - 1 = 11\n3x = 12 (add 1 to both sides)\nx = 4 (divide both side by 3)\n\nNow plug that into the second equation\nx² + x\n4² + 4\n16 + 4\n\nThe answer (assuming you meant x² + x) is 20!

Use the quadratic formula.\nx1 = 1\nx2 = -1/2

Here's the best I can do to help with the first one.\n   __x_+9___\nx-2)X^2+7x-2\n    x^2-2x\n    ------\n        9x-2\n        9x-18\n        -----\n           16\nFollow the example for the rest

(x^2+4x+1)/(x-2) = x+2+3/(x-2)\n\nx  : x^2+4x+1-x^2-2x =2x+1\n2  : 2x+1 -2x-4 =3

4x + 6 is not quite right\nwatch the order of operations and distributive properties\n\nrepost your answer and I'll tell you if you got it\n\n(you didn't think I'd just give up the answer, did you ?)

(2x-9)(2x+9)\n\na guess... its been a long time since I did that stuff

Multiply each term in the first () by each term in the second ():\n\n2x times 2x = 4x^2\n2x times 1 = 2x\n-3 times 2x = -6x\n-3 times 1 = -3\n\nThen combine 2x and -6x\nAnswer: 4x^2 - 4x - 3

you sure you have this problem right ???????\n\nhere's what i came up with\n\nm + ( m + 3 ) = ( m - 2 ) - ( m - 1 ) \nthis is wrong \n\nm + ( m + 3 ) = 2m + 3\n\n( m - 2 ) - ( m - 1 ) \n\n= ( m - 2 ) ( m + 12 ) \n\n= m^2  + 1m - 2m  + 2 \n\n= m^2 - 1m + 2

Look at it this way:\n(-1)*(6x + 6x) = (-1)*(12x) = -12x

ask a question! I can help! maybe... yeah, pretty sure I can, I'm in Algebra 2!

Ok, Victoria, if you're going to ask for help you have to write the questions correctly.  Problem 1 cannot be solved using algebra the way you wrote it, I doubt you can use complex integration or any other advanced tool to solve that one.  Unfortunately, I just spent the last half hour manipulating it before I remembered that little fact.\n\nPut parentheses in.  Had you put the parentheses in the problem would have been trivial.  Kudos to the helpers who were smarter than I in figuring out the constants were in the exponent.  It's not that hard Victoria, especially when you're asking for help.\n\nWrite the question correctly.\n\n\nPS. Irma, you forgot to multiply the 2 from 4=2^2 through the whole parenthetical statement.  The answer is x=4.\n.

You got it right so far. But next...to multiply by 1/4...is the same thing as dividing by 4. So take 4x^2/4=x^2 and then -4/4=-1...so you get x^2-1...make sense? I hope I helped...God bless.
