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 20x plus 5-20 equals 21x plus 4?
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
What is the factorization of this trinomial 2x2 plus 21x plus 49?
2x2 + 21x + 49 = 2x2 +14x +7x + 49 = 2x(x + 7) + 7(x + 7) = (2x + 7)(x + 7)
What is the answer to 3x-24x plus 5 plus 3?
3x - 24x + 5 + 3 = -21x + 8
How do you factorize 7ksquare plus 9k?
k(7k + 9)
How do you factor 21x 35?
To factor the expression 21x^35, you need to find the common factors of 21 and x^35. The factors of 21 are 1, 3, 7, and 21. The factors of x^35 are x, x^2, x^3, ..., x^35. Therefore, the factored form of 21x^35 is 21x*x^34 or 21x^(35-1).
What is the factorization of the trinomial below2x2 plus 21x plus 49?
2x2+21x+49 = (2x+7)(x+7)
What does x equal when 21x plus 9 equals 180?
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
How do you factorise 14xy-21x plus 7?
14xy - 21x + 7 '7' is a common factor to all three coefficients. So 'take it out'. Hence 7(2xy - 3x + 1) The rest of it , inside the brackets does not factor. However, I suspect the 'y' should be a 'power of 2' Hence 7(2x^(2) - 3x + 1) This factors to 7(2x - 1)(x - 1) Fully factored.!!!!
What is the answer to 21x plus 452 equals 32-84x?
21x+452 = 32-84x 21x+84x = 32-452 105x = -420 x = -4
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
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
What is the answer to 20x plus 5-20 equals 21x plus 4?
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
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.
