5X + 9 5(3) + 9 15 + 9 = 24 ====
It is 5x - 4
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
If you mean: x^2 +5x +4 then it is (x+4)(x+1) when factored
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
5X + 9 5(3) + 9 15 + 9 = 24 ====
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).
It is 5x - 4
5x + 3 - 4 + 4x = 9x -1
4 + 8x
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
5x^2 + 20x
If you mean: x^2 +5x +4 then it is (x+4)(x+1) when factored
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
5x + 4 - 3x + 5 + 2x - 9 = 4x
The factorization of 25x2 + 40x + 16 is (5x+4)(5x+4).
