The "4-D" indicates you have an early Federal Reserve Note; those are the code number and letter for the Cleveland OH district. There's more information at the question "What is the value of a 1914 US 5 dollar Federal Reserve Note?".
The expression (-4d - 3) cannot be simplified further without knowing the value of (d). It represents a linear expression where (-4d) indicates a term dependent on (d), and (-3) is a constant. If you have a specific value for (d), you can substitute it into the expression to find a numerical answer.
It is an equation and the value of d is 2
5+3 = 4d 4d = 8 Divide both sides by 4 to find the value of d: d = 2
8 - 4d = 12-4d = 4d = -1
To find the value of (2c + 4d) when (c = 30) and (d = 8), substitute the values into the expression. This gives you (2(30) + 4(8) = 60 + 32 = 92). Therefore, (2c + 4d = 92).
4d is time...any moving object is 4d
The value of a 1990 $100 bill with a serial number starting with "4D" can vary based on its condition and any unique features it may have. In general, if the bill is in circulation and shows signs of wear, it may be worth its face value of $100. However, if it is in uncirculated condition or has collector appeal, it could be worth more, potentially ranging from $100 to several hundred dollars. For a precise evaluation, consulting a currency expert or a pricing guide is recommended.
there is no 4d known to man
2-4d = -2
They are a, a+d, a+2d, a+3d and a+4d where a is the starting value and d is the common difference.
Sometimes you only see 4D for short times, normally our 3D in 4D surface is not contacted, and sometimes it can be that the 4D thing stays on.
To determine how much 4d (four pence) is in today's money, we can convert it to modern currency. In the UK, 4d is equivalent to 1/5 of a shilling, or 1/60 of a pound. Today, this would be roughly equivalent to 1.67 pence, considering inflation and changes in currency value over time. However, the exact value can vary based on historical context and specific inflation calculations.
