Answer:
2x+10 is the first answer
2x+8 is the second
8 and 36 is the last
The perimeter of the framed picture expressed in terms of x will be 36 + 4x
Recall :
Perimeter of a rectangle = 2(length + width)
Length of picture = 10
Width of picture = 8
Width of frame = x
Hence, the dimension of the framed picture will be :
Picture dimension + frame dimension
Length of framed picture = 10 + x
Width of framed picture = 8 + x
Perimeter of framed picture :
2[(10+x) + (8+x)]
2[(10 + x + 8 + x]
2[18 + 2x]
36 + 4x
Hence, the perimeter of the framed picture will be : 36 + 4x
