What is 8 more than 3 times the number?
To express "8 more than 3 times the number," you start with the variable representing the number, let's call it ( x ). Three times the number is ( 3x ), and adding 8 gives you the expression ( 3x + 8 ). Thus, the answer is ( 3x + 8 ).
How do you write 8 more than 3 times a number?
To express "8 more than 3 times a number," first represent the unknown number as a variable, such as ( x ). Then, "3 times a number" is written as ( 3x ). Finally, adding 8 gives the expression ( 3x + 8 ).
How many times does 8 and 3 go in to 49?
Exactly, 5x 8 + 3x 3
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 math answer to the math problem 4(3x 2) 4x?
To solve the expression (4(3x + 2) + 4x), first distribute the 4: [ 4 \times 3x + 4 \times 2 + 4x = 12x + 8 + 4x. ] Next, combine like terms: [ 12x + 4x + 8 = 16x + 8. ] So the simplified answer is (16x + 8).
