Answer:
X=7
Step-by-step explanation:
HJ + JK = HK
3(X + 2) +(3X - 4) = 44
3X + 6 + 3X - 4 = 44
6X + 2 = 44
6X = 42
X = 7
Combine like terms first
2x+ 424+4
2x+ 428 (answer)
Answer: 128 
Step-by-step explanation:
Let the width be W then the length will be 2W since it is twice as long as it width.
The formula for calculating the perimeter of a rectangle is given by :
P = 2 ( L + W )
48 = 2 ( W + 2W )
48 = 2(3W)
48 = 6W
Divide through by 6
Therefore:
W = 48/6
W = 8 inches
This means that the Length is 2 x 8 = 16 inches
Area = Length x breadth
Area = 16 x 8
Area = 128
