write expressions in simplest form...4r^2-25s^2/2r^2+3rs-20s^2...please help?

Consider holding down the Alt key whilst typing 253 on the numeric keypad - it would make this easier to read:\n4r²-25s²/2r²+3rs-20s\nor should it be:\n4r²-25s²/(2r²)+3rs-20s\nor:\n4r²-25s²\n--------\n2r²+3rs-20s

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]

Just multiply:\n(X/3)(3/4 x) -(x/3)(3/5) + (3/4)(3/4x) - (3/4)(3/5)\n\nand simplify from there

if you want to simplify it \n\nit is 3x - 4x + 4 = -x + 4

-24+w+8=4\n-24+24+w+8-8=4+24-8\nw=20\n\nhope this helps!

You end up with a remainder, so it's not pretty, but you should be able to do long division and get:\n\n3x^2 - 4x + (16/3) - 23/(3*(3x+2))

You want to basically simplify the expression through taking out a common factor of each term in that expression:\n\nso 4 goes into both 4a and 16\nso 4(a+4) I believe would be the correct answer. \nDon't get mad if I'm wrong.

If u could give the entire question i could solve it for u and i'm not jokin. its actually quite easy.Its basically\n\n(w+3)/4w * 2w/(w-3).So wat ud have is\n\n1/2( (w+3)/(w-3) )\n\nits xactly like sayin 2/4 = (2/1) / (4/1)
