(x + 4) + (x + 5) = 2x + 9
x + 5 + 4 = x + 9
If you mean: x+4(x+5) then it is 5x+20
3 plus 4 x plus 5 31 when simplified would give x = 23/4.
x+4x+5=5x+5
x + 5 + 4 = x + 9
If you mean: x+4(x+5) then it is 5x+20
(x + 4) + (x + 5) = 2x + 9
If its x+4x+5 then: 5x+5
x+4x+5=5x+5
If: x+(-5) = 4 Then: x = 9
(x + 4) / (x3 - 11x + 20) = (x + 4) / (x2 + 4x - 5)(x + 4) = 1 / (x2 + 4x - 5) = 1 / (x + 5)(x - 1), where x ≠ -4
2x+5=3x+1 -x=-4 x=4
Problem: x+5x+4Answer:6x+4Explanation: You have 5 x's...you add the other x to the 5 x's and that makes 6 x's...then the +4 stays the same because you have nothing to combine it with. So therefore, your answer would be 6x+4.
x+4x+5 = 0 5x + 5 = 0 5x = -5 x = -1
no...why would it.... it equals 2x+9
x2 + 9x + 20 = 0 ∴(x + 4)(x + 5) = 0 ∴x ∈ {-5, -4}
