Is there some other part of this ?
Answer:
2
Step-by-step explanation:
Perimeter of a rectangle = 2(length + breadth)
=> 2{2x + (x + 4)) = 20
=> (2x + x + 4) = 20/2 = 10
=> 3x + 4 = 10
=> 3x = 10 - 4 = 6
=> x = 6/3 = 2
Here, according to the diagram
Length = 2x = 2(2) = 4
Breadth = x + 4 = 2+4 = 6
But breadth should always be lesser than the length. From this, it can be concluded that the actual breadth is 2x and actual length is x + 4, for perimeter to be 20.
Answer:6
Step-by-step explanation:
Answer:
No solution
Step-by-step explanation:
Add x and 2x.
3x+9=3x+11
Move all terms containing x to the left side of the equation.
Subtract 3x from both sides of the equation.
3x+9−3x=11
Combine the opposite terms in
3x+9−3x.
Subtract 3x from 3x.
0+9=11
Add 0 and 9.
9=11
Since 9≠11, there are no solutions.
