If the sum is negative or if the signs are different and the negative has a biger absoulute value.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>Let's find 'a' using Pythagoras theorem.</u>
- => 4² = 2² + a²
- => 16 = 4 + a²
- => 12 = a²
- => a = √12
- => a = √2 x 2 x 3
- => a = 2√3
- => a = 2 x √3
- => a = 2 x 1.732
- => a = 3.464 = 3.5 (Estimated)

Answer:
![WoodLength = 50w + 20](https://tex.z-dn.net/?f=WoodLength%20%3D%2050w%20%2B%2020)
Step-by-step explanation:
Given
Length of Pieces = 50cm
Number of Pieces = w
Left over = 20cm
Required
Determine the length of the wood
Start by multiplying the number of pieces by the length of each pieces
![Result = Length * Number](https://tex.z-dn.net/?f=Result%20%3D%20Length%20%2A%20Number)
![Result = 50 * w](https://tex.z-dn.net/?f=Result%20%3D%2050%20%2A%20w)
![Result = 50 w](https://tex.z-dn.net/?f=Result%20%3D%2050%20w)
Lastly, add the leftover to get the actual length of the wood
![Wood Length = Result + Leftover](https://tex.z-dn.net/?f=Wood%20Length%20%3D%20Result%20%2B%20Leftover)
Substitute 50w for Result and 20 for Leftover
![WoodLength = 50w + 20](https://tex.z-dn.net/?f=WoodLength%20%3D%2050w%20%2B%2020)
<em>Hence, the length of the wood is 50w + 20</em>
