Subtract 8 from the product of x and 3?
8
3x plus 8 equals 20-3x what is x?
3x + x + 8 = 204x + 8 = 204x = 12x = 3
The product of your number and 3 is the same product as twice 9 What is your number?
3x = 2 x 9 2 x 9 = 18 3x = 18 18/x = 6 Therefore, x = 6
If 4 is added to twice a number and this sum is multiplied by 2 the result is the same as if the number is multiplied by 3 and 4 is added to the product What is the number?
Let the number be x: 2(2x+4) = 3x+4 4x+8 = 3x+4 4x-3x = 4-8 x = -4
Which is the complete factorization of the trinomial 3x 2 10x8?
3x^2 + 10x + 8 = (3x + 4)(x + 2)
What is 3x-2y equals 8?
It is an open sentence. 3x = 3 x X 2y = 2 x Y, If 8 is the product then: x = 4 and y = 2. 3 x 4 = 12 2 x 2 = 4 12- 4 = 8
What is 3x - 2 equals x plus 8?
3x-2=x+8 (+2) 3x=x+10 (-x) 2x=10 (/2) x=5
Subtract 8 from the product of x and 3?
8
How do you solve 3x2 plus 10x equals 8 by factoring?
3x² + 10x = 8 Rewrite as: 3x² + 10x - 8 = 0 The only way to get 3x² is 3x and x (3x + -- ) (x + --) The factors of 8 are {1 2 4 8} so the answers must be a pair of them. With 4 factors, and a negative sign (the -8), there are only 8 ways this can be written: (3x + 1)(x - 8) = 3x² - 23x - 8 (3x + 2)(x - 4) = 3x² -10x - 8 (almost) (3x + 4 )(x - 2) = 3x² - 8x - 8 (3x + 8)(x - 1) = 3x² +5x - 8 (3x - 1)(x + 8) = 3x² +23x - 8 (3x - 2)(x + 4) = 3x² + 10x -8 ◄ Success! (3x - 4)(x + 2) = 3x² +2x - 8 (3x - 8)(x + 1) = 3x² -5x - 8 Trial and error, error, error, is the key to this kind of problem. Seeing the -10x early can point you to see that maybe changing the signs can work. ■
What is the solution of y x 4 y 3x 8?
If you mean: y = x+4 and y = 3x+8 then x = -2 and y = 2
3x plus 8 equals 20-3x what is x?
3x + x + 8 = 204x + 8 = 204x = 12x = 3
What expression is equivalant to -2 x-2?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
How do you find the product (3x-1)(x plus 5)?
The product of (3x-1)(x+5) = 3x^2 +14x -5 by multiply out the brackets
Solve the equation for x 6x plus 6 equals 3x - 2?
6x + 6 = 3x - 2 Bring 3x to the left and subtract: 6x - 3x = 3x 3x + 6 = -2 -2 - 6 = -8 -8 / 3 X = -8/3
Factor this polynomial completely 3x2 plus 2x - 8?
3x2 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x+2) - 4(x+2) = (3x-4)*(x+2)
-3x plus 2 equals 2x-8?
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
What's equivalent to 3x plus 2 8?
If you mean: 3x+2 = 8 then x = 2
