Divide it by 3 then times by 2. 84 divided by 3=28x2=56 :)
"Yes 28 x 2 = 46"..............28x2=56...not 46 O.o just sayin
7 7x2=14 14x2=28 28x2=56
-10/7. assuming this pattern keeps going. this is actually a very interesting pattern going 14 (7x2) 28 (14x2) 56 (28x2) 112 (56x2) 224 (112x2) ... If you can see, its 1.4 (7x2) 28 (14x2) 57 (28x2+ 1) (1)14 (56x2 +2) (2)29 (112x2 +5 (guess where that 5 came from ;) )
2 x 2 x 3 x 2 x 2 x 7 x 2 x 2 x 2 = 27 x 3 x 7 or 2688
28x^2 - 47x = 15 28x^2 - 47x - 15 = 0 ax^2 + bx +c = 0, so: a = 28 b = -47 c = -15 quadratic formula: [-b^2 + sqrt(4*a*c)] / 2*a AND [-b^2 - sqrt(4*a*c)] / 2*a [47^2 + sqrt(4*28*-15)] / 2*28 AND [47^2 - sqrt(4*28*-15)] / 2*28 then just do the math
Error: There cant be two x's in a equation either one to be y and other x or some other variable.Sure there can be two x's. There is no '=' in this question anyway, so it is not an equation. You cannot solve for x with the information given, but you can simplify it as follows.Performing the operations in proper order (exponents, then multiplication (and division, if any), and lastly the addition/subtraction operations, gives you:x +(7x) + (7)(4) (x2)Which is 8x + [28 (x2)] or 8x + 28x2 .
To find the common multiples, we first need to break the numbers down into their prime factors: 14 = 2x7 28 = 2x2x7 The next step is to identify any common factors. In this case, both numbers have a single 2 and a single 7, so we can discard one of each. This leaves us with 2, 2 and 7. Multiply these together for the LCM: 2x2x7 = 28 To find other multiples, you now simply multiply this number by any integer. For instance, 28x2, 28x3, 28x4.... Thus the first few common multiples of 14 and 28 are 28, 56, 84, 112.

3 AND -4/7 are solutions to the equation (but because the question asked for the integer that satisfies the equation only 3 is correct since -4/7 is not an integer). Let x be the number. Solve the following equation for x: (1/2x)+(1/(2x+2))=7/24 [Now you need a common denominator on the left side, so and multiply the second term by (2x) in the numerator and the denominator.] (2x+2)/(2x(2x+2))+(2x/(2x(2x+2))=7/24 [Now multiply both sides by (2x(2x+2)) and 24 to clear the denominators on both sides.] 24*(2x+2+2x)=7*2x(2x+2) [Multiply out the left and right sides and combine terms to simplify.] 96x+48=28x2+28x [Divide both side by four and solve the quadratic equation.] 24x+12=7x2+7x 7x2-17x-12=0 [The easiest way to solve this (if the factorization is not obvious) is to us the quadratic equation.] x=(17+/-sqrt(172-4*7*(-12)))/(2*7) x=(17+/-sqrt(289+336))/(14) x=(17+/-25)/(14) x=42/14=3 OR x=-8/14=-4/7 Instead of the quadratic equation, you can observe that the above quadratic equation can be factored into: (x-3)(7x+4)=0, which yields the same solutions. The A+ answer is 3.
