4_4_4_4=20 some one tell me how?

4*(4/4+4)=\n4*(1+4)=\n4*5=\n20

5x4+4+4+5+4/2\n=20+4+4+5+2\n=35

n! =n*n-1*n-2...until you get to zero.\n\nso 4! equals 4*3*2*1\nwhich is 24

subtract 4f from both sides so its now 4f=32 so f is 8

4000(1 + .06/4)^4*x\n4000(1 +.06/4)^20 = $21227.27\n\n4000(1 + .08/4)^4*x \n4000(1 + .08/4)^20 = $21648.64

b^2 - 4ac\n= (-4)^2 - 4(2)(-3)\n= 16 + 24\n= 40\nRoots are real and distinct.

when x = 4, the formula would be\n\ny=5/4 ( 4 )\ny = 20 / 4 = 5

(4/x-8/y)/(24/xy)\n=(4y-8x/xy) * xy/24\n= 4(y-2x)/xy * xy/24\n=(y-2x)/6

12/4 = 60/20\n4/5= 16/20\n60/20-16/20= 44/20\n44/20= 2 4/20\n2 4/20= 2 1/5\nso the answer is 2 1/5! :)\nyou need to simplify the 11/5 which makes it 2 and 1/5

4a + 3b = 4x4 + 3x(-4) = 16 - 12 = 4

U R RIGHTT..HOW DID YA GET IT..PLZ CAN YA EXPLAIN..I'VE BEEN TRYING THIS PROBLEM FROM A LONGTIME.EVEN DE CALCULATOR SAYS ITZ "4"..I KNOW DE CALCULATORS WRONG TOO..PLZZ DO EXPLAIN IT TO ME ASAP

f(4) means 'rewrite f(x) = 2x - 5 with a "4" instead of an "x"', like this:\n\nf(4) = (2 * 4) - 5\n=8 - 5\n=3

ok\nf(x) = 20 - x\nf(0) = 20 - 0 = 20\nf(2) = 20 - 2 = 18\nf(4) = 20 - 4 = 16\nf(8) = 20 - 8 = 12

let's say u=4^x\nso the equation becomes:\nu^2-20u+64=0\n(u-16)(u-4)=0\nu=16 or u=4\n\nsubstitute 4^x in to get:\n4^x=16 or 4^x=4\n\nthus, x=2 or x=1
