Unless you want a remainder, which would be x-3 + 5/(x+3)  A simple way to do this problem would be to factor x^2-x-12 into (x+3)(x-4) we can then write: (x+3)(x-4)/(x-4) and then the (x-4) in the top and bottom of the fraction both cancel leaving just x+3 as the solution.   3 plus 4 x plus 5 31 when simplified would give x = 23/4. okay if x-4=3 then x=7 bcause 4+3=x = 4+3=7 and 7-4=3! Since 4 x 3 = 12, common multiples of 4 and 3 are the multiples of 12. The first five of these are: 12 = 4 x 3, 3 x 4 24 = 4 x 6, 3 x 8 36 = 4 x 9, 3 x 12 48 = 4 x 12, 3 x 16 60 = 4 x 15, 3 x 20 If you mean: 3(x+5) = 4(x-2) then the value of x works out as 23 "Square" means to times it itself twice. For example, if I were to square 3, it would be 3 x 3. If I were to square four, it would be 4 x 4. Now, to provide a little more information, "cubed" means to times itself three times. So if I were to cube 3, it would be 3 x 3 x 3. If I were to cube four, it would mean 4 x 4 x 4. These are called exponents. Exponents are numbers above the base. Typing, it would be, take 3, for example, 3^2 if you wanted it to be squared. If it would be cubed, it would be typed as 3^3. The first number is the main number, or the base, and the second number, or exponent, is how many to times the base by. For example, 3^2 would mean 3 x 3. The exponent, in writing, would be in smaller text hovering next to the base, just as if you were to write 3rd. Volume of a sphere = 4/3 x pi x radius3; (4/3) x 3.1416 x (10 inches)3 = (4/3) x 3.1416 x 1,000 cubic inches = 4,188.8 cubic inches (x - 3)/(12 - 4x) = (x - 3)/[4(3 - x)] = (x - 3)/[-4(x - 3)] = 1/-4 = -(1/4) 3 x 2 x 4 = 24 (3 x 2) x 4 = 6 x 4 = 24 3 x (2 x 4) = 3 x 8 = 24 2 x (3 x 4) = 2 x 12 = 24 ( 3/4 ) x ( 3/4 ) = ( 3 x 3 ) / ( 4 x 4 ) = 9/16 x^(-5/3) = 4 1/x^(5/3) = 4 x^(5/3) = 1/4 [x^(5/3)]^(3/5) = (1/4)^(3/5) x = 1/4^(3/5) or, x = 4^(-3/5) Check: x^(-5/3) = 4 [4^(-3/5)]^(-5/3) = 4 ? 4 ^(15/15) = 4 ? 4^1 = 4 ? 4 = 4 x/3 + x = 4 times all by 3 x +3x = 12 add the two x's together 4x=12 divide by 4 x=3 test your work 3/3 + 3 =4 1+3=4 4=4   One solution is 8 x (4 - 3/3) = 8 x (4 - 1) = 8 x 3 = 24 And another, 8 x 3 x (4 - 3) = 8 x 3 x 1 = 24 And a third, (3 + 3) x ( 8 - 4) = 6 x 4 = 24 4-3+x=y; I would write as an equation of y in terms of x. So, subtract 3 from 4 gives 1. Therefore 1+x=y or as more commonly written y=x+1.  no 27 = 3 x 3 x 3 64 = 4 x 4 x 4 let the number be x.x/-4 = -3x= -4 X -3x = 12 It would be the length x width x height. length = 3 feet. width = 3 feet. height = 4 feet. So the volume is 3 x 3 x 4 feet3, which is 36 feet3.
