2x square plus 21x plus 49?
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
Where does y equals 3x-5 and 21x-35 equals 7y intersect on a graph?
put both equations in standard form y - 3x = -5 (equation 1) -7y + 21x = 35 (equation 2) multiply equation 1 by 7 (this is done so either one of your variables will cancel... if both variables cancel then these lines are parallel) 7y - 21x = -35 -7y + 21x = 35 0 = 0 therefore your lines are parallel
What is the GCF of 14x and 21x?
7x
What is the factor of 3x plus 21x plus 9x?
3x+21x+9x=33x. Break it apart. The factor of x is x and the factors of 33 are 3 and 11. Therefore, the factors of 3x+21x+9x are 3, 11, and x.
What is 7x times 3x?
21x^2
How many square feet equals to 21x 16 feet?
You simply multiply the two measurements: 21 x 16 = 336 (square feet).
What does x equal when 21x plus 9 equals 180?
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
What is the answer to 9x equals 21x-3?
If: 9x = 21x-3 Then: x = 1/4 or 0.25
What is -21x equals -126?
105
What is the answer to 21x plus 452 equals 32-84x?
21x+452 = 32-84x 21x+84x = 32-452 105x = -420 x = -4
What are the solutions of x2 minus 21x equals 72?
x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
What is 21x equals 6x plus 30?
234 it is not the answer
How do you factor 20x squared -5 equals 21x?
Make it equal zero by subtracting 21x from both sides. 20x2 - 21x - 5 factors to (4x - 5)(5x + 1)
What are the solutions for the quadratic equation x2 minus 21x equals 72?
x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
What is the answer to 20x plus 5-20 equals 21x plus 4?
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
How do you solve 21x-7y equals 4?
You plot the equation as a graph. Every one of the infinitely many points on the graph is a solution.
What answer 21x plus 12x - 2 equals?
21x + 12x -2 = 0 33x -2 = 0 33x = 2 x = 2/33 x = 0.06
