What is 4x plus -12 equals 8?
If: 4x+(-12) = 8 then 4x = 20 and x = 5
What is 3x plus 5 equals 4x plus 1?
If: 3x+5 = 4x+1 Then: x = 4
What is 4x - 7 5?
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
If 4X - 7 equals 2X plus 5 what is the value of x?
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
What does 4x plus 5 plus 2x equal?
6x + 5
X2 plus y2 plus 4x - 2y - 5 equals 0?
No.
How do you simplify the equation x2 plus 4x-5 divided by x plus 5 I am stuck?
x+5 is a factor of x2+4x-5 use synthetic division to learn that the other factor is x-1
6x-12 plus 4x plus 5?
6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10
What is 3x4 plus 5x3 plus x2 - 5 divided by x 2?
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
How do you factor x2 plus 4x-5 equals 0?
X2 + 4X - 5 = 0 what two factor of - 5 add up to 4? (X - 1)(X + 5) ----------------- ( so, X = 1 and X = - 5 )
What is 4x plus -12 equals 8?
If: 4x+(-12) = 8 then 4x = 20 and x = 5
How do you you factor 4x3 plus 16x2 -180x?
4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)
What is the factor of 4x2 plus 17x plus 15?
(x + 3)(4x + 5)
What is x2 plus x2 mean?
If you have an equation of x2 plus x2, it is the same as saying 2 times x plus 2 times x. This can be written as 2x + 2x or x2 + x2. It is the same, then, as 4x. For example, if x equals 5: 2(5) + 2(5) = 10 + 10 = 20. 20 also equals 4(5).
What is x plus 4 divided by x3 -11x plus 20?
(x + 4) / (x3 - 11x + 20) = (x + 4) / (x2 + 4x - 5)(x + 4) = 1 / (x2 + 4x - 5) = 1 / (x + 5)(x - 1), where x ≠ -4
What number must you add to complete the square x2 plus 4x equals 5?
Add 4 to both sides. To complete the square, take half the x coefficient into the bracket: (x + 4/2)2 = (x + 2)2 = x2 + 4x + 4 Comparing with the original, need to add 4 to both sides of x2 + 4x = 5: (x2 + 4x) + 4 = (5) + 4 ⇒ x2 + 4x + 4 = 9 ⇒ (x + 2)2 = 9
What are the solutions to the equation x2 plus 4x-9 equals x plus 1?
x = 2 and x = -5
