Answer:
brainliest plzzzzz
Step-by-step explanation:
2(x-2) - 3(x-4)
Simplify:
2(x-2)-3(x-4)
2x-4-3(x-4)
Distribute:
2x-4-3(x-4)
2x-4-3x+12
Add the numbers:
2x-4-3x+12
2x+8-3x
Combine like terms:
2x+8-3x
-x+8
Hence Solution = -x+8
Answer: The lenght of the missing side is 4 cm
Step-by-step explanation:
The correct question is:
<em>The perimeter of the rectangle is 20cm . One side is 6cm. What is the length of the missing side?</em>
So, to answer it we have to apply the next formula:
Perimeter of a rectangle = 2 width + 2 length
Replacing with the values given: (assuming that the side given is the length of the rectangle)
20 = 2(6) + 2x
Solving for x:
20 =12 +2x
20-12 =2x
8 =2x
8/2 =x
4=x
The length of the missing side is 4 cm
