The secret is to understand some of the rules of logarithms and adjust translate the numbers to make your lob easier.\n\nThe rules:\nlog(a*b) = log(a) + log(b)\nlog(a/b) = log(a)- log(b)\nlog(a^n)=nlog(a)\n\nIf I understand your problem:\n\nx= [(86400)*sqrt(365.25)]/[ (.079)^11]\n\nso log(x) = log [.....]\n\n     = log(86400)+log(356.25^.5) - log(0.79^11)\n     = log(86400)+.5*log(356.25) - 11*log(0.79)\n\nuse log tables to get the logs and add them up to get the log of x.  Use the tables again to find x.\n\nYou can make other approximations, i.e., 356.25 is close to 19^2 (=361)\nand 86400 is close to 300^2 (=90000) and continue from there.  \n\nHope that helps.

SA = 2lw + 2lh + 2wh\n= 2(lw+lh+wh)\n= 2(8*6 + 8*2 + 6*2)\n= 2(48+16+12)\n= 2(76)\n= 152 centimeters squared

ALAN = X candies\nBARBARA = X+7\nCLAUDE = 2(X + 7)\nX + X+7 + 2(X+7)= 329\n4X+21 =329\n4X=308\nX=77\n\nALAN = 77\nBARBARA = 84\nCLAUDE = 168\n\n  168\n + 84\n + 77\n=329

Multiply all the way through by 12, the L.C.M. of 2, 3 and 4.\nSo\n72 + 6(x-1) - 4(x-2) = 3(3-x)\n\nNow multiply out brackets:\n\n72 + 6x - 6 - 4x + 8 = 9 - 3x\n\nSimplify the left-hand side:\n\n74 + 2x = 9 - 3x\n\nNow take the x's to the L.H.S. and numbers to the other side:\n\n5x = -65\nwhich gives x = -13

just plug the numbers in.  if y=8, and x=2, \nits 8=a(2^2)\nso 8=a(4)\nso a=2.\nhope that helps!

Easy.  You think of any number X.\n\nThey make you add 23, add 16, subtract 17, add 2, add 14 and subtract you number.\n\nSo the answer you will always get it\n\nX + 23 + 16 - 17 + 2 + 14 - X = 38\n\nAlgebra is fun!!! lol...NOT

Ok, first you must get the -8 and the x/-2 out of parentheses, so u just multiply them both by one. So then is -8 * x / -2. First, you do -8 * x, which is -8x. The problem then becomes -8x / 2. In this step, just don't mind the negative or the x and just put them back in at the end. So you're really just doing 8 / 2, which is 4. You must put the - and the x back in, so the answer is -4x. Ta Da!

P = 2 L + 2 W\nL = 2 W + 8\n2W + (4 W + 16) = 64\nW = 8

ur second equation is wrong. \n2a is not equal to a-squared (which u symbolized by ab, since a=b).

i think this formula works.\nfactorial of A-4A\nso.using this formula the correct answer is 5012

2 * (l + w) = perimeter of rectangle\nl * w       = area of rectangle\nPerimeter of rectangle = Area in sqr units\n=> 2 * (l +w) = l * w\n=> 2*l + 2*w = l*w\n=> 18 + 2 * (x+1) = 9 * ( x +1 ) since l = 9 and w = x + 1\n=> 18 + 2x + 2 = 9x +9\n=>  11 = 7x\nHence x = 11/7

(x + 4y)(x - 4y)\nI answered 2 of your questions. Do the rest of the questions yourself.

Ok...\nI see what you are doing...\nYou merely substitute the number in for x...\nso the problem becomes 6-2*(-1)\n6+2\n8

2...... 2....... 2 (2 is the square root)\nx  =17 .. +  ..10\ndo the same for the next one\nu can solve the equation ,I know u can
