What is the exact solution for x-12 equals 91-84?
x - 12 = 91 - 84x - 12 = 7x = 19
Solve x in the following 3x14 equals 84x x?
(3)(14) = 84x 42 =84X x=1/2
What consecutive whole numbers total 84?
x + (x + 1) + (x + 2) = 843x + 3 = 84x = 2727 + 28 + 29 = 84x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6)= 847x + 21 = 84x = 99 + 10 + 11 + 12 + 13 + 14 + 15 = 848x + 28 = 84x = 77 + 8 + 9 + 10 + 11 + 12 + 13 + 14 = 84

How do you factor 49x squared minus 84x plus 36?
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
What is 2x-84x 1?
-82X, and you're missing an operator there.
What is the LCM of 7x and 12x?
Since x is a factor of both numbers, ignore it and find the LCM of 7 & 12. These two numbers do not share any factors, so their LCM is 7*12 = 84. Put the x back in for the final answer - 84x.
3x - 8 12 - x?
I assume you mean 3x - 8 = 12 - xif we move the x's to one side and the numbers to the other side:3x - 8 + x = 12 - x + x4x - 8 = 124x - 8 + 8= 12 +84x = 204x/4 = 20/4x = 5I hope that answers your question but if you would like further information please email me at charris321@wikianswers.com
What part of a group of equations is 49x squared plus 84x plus 36?
It is a quadratic expression and it is (7x+6)(7x+6) when factored
What is the area of a square that has a side of 6x 7?
Thanks to limitations of the browser used for posting questions, it is not possible to tell whether the sides are 6x - 7 units or 6x + 7 units. For 6x - 7 units, area = 36x2 - 84x + 49 square units. For 6x + 7 units, area = 36x2 + 84x + 49 square units.
Solve for x in the following 3 over14 equals 84?
In order to solve for x, there must be an x in the equation.If you meant to say 3x/14=84, then 3x=14(84), so x=392 If you meant to say 3/14x=84, then 84x=3/14, so x=0.00255102041 If you meant to say 3/14=84x, then the above line is the answer.
What is the equation of the function of the parabola that contains the points 0 0 20 12 0 40?
As there is a repeated x-coordinate, x = f(y), giving:As it is a parabola, x = ay² + by + c, so substituting the known points:(0, 0) → 0 = 0²x + 0b + c → 0 = c(20, 12) → 20 = 12²a + 12b + c → 20 = 144a + 12b + c(0, 40) → 0 = 40²a + 40b + c → 0 = 1600a + 40b + cFrom equation 1, c = 0, so substituting in the second and third equations gives two new equations involving two unknowns:20 = 144a + 12b0 = 1600a + 40bThe second of these can be simplified to give: 0 = 40a + b→ b = -40aThis can be substituted back into the first to give:20 = 144a + 12 b→ 20 = 144a + 12(-40a)→ 20 = 144a - 480a→ 20 = -336a→ a = -5/84→ b = -40a = -40(-5/84) = 50/21→ x = -5/84 y² + 50/21 y→ 84x = -5y² + 200y→ 84x = 200y - 5y²The parabola has equation 84x = 200y - 5y²
