8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
52 = 2x + (6x +4) 52 = 2x + 6x + 4 (can skip this step) 52 = 8x + 4 52 - 4 = 8x 48 = 8x 48/8 = x (can skip this step) 6 = x
x= -1
2x2 = 8x x = 8x/2x x = 4 Check: 2(4)2 = 8(4) 2(16) = 32 32 = 32
-6x-32 = 2x -6x-2x = 32 -8x = 32 x = -4
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
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 = 24Given x = 5, 2x * 4 = 2(5) * 4 = 10 * 4 = 40------------------------------------------------------------------------------------------------------------------Contrary to the answer above; 2x * 4 = 8x
(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)
52 = 2x + (6x +4) 52 = 2x + 6x + 4 (can skip this step) 52 = 8x + 4 52 - 4 = 8x 48 = 8x 48/8 = x (can skip this step) 6 = x
5x + 5 - 8x - 8x + 4 = 9 - 11x
3x + 2x - 8x + 2x = -x
x= -1
(4x + 12)/(8x - 4y) = [4(x) + 4(3)]/(4(2)(x) - 4y] = 4(x + 3)/4(2x - y) = (x+ 3)/(2x - y)
Do you mean 2x²? Assuming this is the case: 2x² - 3x + 8x - 12 = 2x² + 5x - 12 = (2x - 3)(x + 4)
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3

4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
