4d, which means that whatever d is, times it by 4 and you will recieve the answer.
C squared times the square root of 5cd over 2 times d to the third power
Each binary digit represents 2 times that of the digit to its right. So for example: 10b = 2d 100b = 4d 1010b = 8d + 2d = 10d
Write the equation of the given line in standard form: y = mx + c so: 3y = 4x - 7 or y = 4/3x - 7/3 The slope of the given line is 4/3. The slope of the line perpendicular to it is the negative reciprocal (change the sign and flip the fraction over). ie the perpendicular has slope -3/4 So the equation of the perpendicular is of the form y = -3/4x + d or 4y = - 3x + 4d or 3x + 4y = 4d. To evaluate the value of the constant d (or 4d) you will need one point on the perpendicular line. Substitute the coordinates of that point for x and y in the above equation and you've got 4d.
i think it is where 2d is flat 3d looks like you can touch it but you cant and 4d is where you can see it and physically touch it
