This question can only be answered with additional information, such as the value of x.
Given x = 3, 2x * 4 = 2(3) * 4 = 6 * 4 = 24
Given x = 5, 2x * 4 = 2(5) * 4 = 10 * 4 = 40
------------------------------------------------------------------------------------------------------------------
Contrary to the answer above; 2x * 4 = 8x
To find the product of 2x and 4, you simply multiply the two numbers together. This results in 8x, as 2 multiplied by 4 equals 8, and the variable x remains unchanged. Therefore, 2x times 4 is equal to 8x.
(3x+1)(2x+4) = 6x2+4+2x+12x = 6x2+14x+4
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
(2x + 4)(2x - 4) to check your answer, use the FOIL method (first, outside, inside, last) F.... 2x x 2x = 4x^2 0.... 2x x -4 = -8x I..... 2x x 4 = 8x L.... 4 x -4 = -16 so 4x^2 - 16 = (2x + 4)(2x - 4)
2x+4 = -16 2x = -16-4 2x = -20 x = -10
2x-6=4 6+4=2x 10=2x 10/2=x 5=x x=5
