What is the value of x if 3x-17 and 3x-25?
1) 3x-17=0 3x=17 x=17/3 2) 3x-25=0 3x=25 x=25/3
X2 over 3x2 -5x-2 -2x over 3 x plus 1 x 1 over x-2?
x2/(3x2 - 5x - 2) - [2x/ (3x + 1)][1/(x - 2)] = x2/(3x2 - 6x + x - 2) - 2x/(3x + 1)(x - 2) = x2/[3x(x - 2) + (x - 2)] - 2x/(3x + 1)(x - 2) = x2/(3x + 1)(x - 2) - 2x/(3x + 1)(x - 2) = (x2 - 2x)/(3x + 1)(x - 2) = x(x - 2)/(3x + 1)(x - 2) = x/(3x + 1)
X² -3x - 28 equals?
-31
What does x equals in 3x 12 equals 18?
3x+12 = 18 3x = 18-12 3x = 6 x = 2
3x equals 96-75 solve for x?
3x = (96-75) 3x = 21So X = 7
How do you distribute 3x(x-4)?
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
What is 3x squared minus 6x divided by 3x?
(3x2 - 6x)/3x = 3x(x-2)/3x = x-2, for x<>0
How do you do (3x 4)2?
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
How do you factor 3x Squared plus x?
3x2 + x = x*(3x + 1)
Simplify x squared plus 3x plus 2 divided by -3x minus x squared minus 2?
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
What is 4X plus X?
4x + -x = 3x
find the measures of an angles of an triangle that are x,3x, and 3x+5?
If the angles are x, 3x and 3x+5, the following equation gives x x+3x+(3x+5)=180 -> x =25, and in degrees the angles are 25, 75 and 80.
What is the answer 3x divided 5-x divided 3 equals 4?
3x/(5-x)/3=4 3x/(5-x)=4X3 3x=12(5-x) 3x=60-12x 3x+12x=60 x=4
How do you do (x squared -2) (x squared 3x 5)?
(x^2-2) (x^2+3x+5)= x^2(x^2+3x+5) -2(x^2+3x+5)= x^4 +3x^3 +5x^2 -2x^2 -6x -10= x^4 +3x^3 +3x^2 -6x -10
What is the answer to x-2 equals 3x plus 1?
x-2=3x+1 x=3x+1+2 x-3x=3 -2x=3 x=-3/2
What is the value of x if 3x-17 and 3x-25?
1) 3x-17=0 3x=17 x=17/3 2) 3x-25=0 3x=25 x=25/3
What is 3x minus x?
3x - x = (3 - 1)x = 2x
