Answer:
x=12
Step-by-step explanation:
use midpoint theorem that said that the small line segment (3x+11) is half of the segment ( 9x -14)
2(3x +11) = 9x -14
6x +22 = 9x -14; distribute
6x -9x = -22-14; subtract 9x and 22 from both sides
-3x = -36; divide both sides by -3
x= 12

Answer:
the new frame is bigger than the original frame by 10%
Step-by-step explanation:
Let the length of the original frame be l,
then it's width is (10% of l)=
×l
=
hence area of original frame=A=length×width
=
now the length of frame is enlarged by 10%
new lenght of frame=l+10%×l
=l+
×l
=
×l
width of new frame==
area of new frame=length×width
=
percent change=((area of new frame-area of old frame)×100)÷area of old frame
=10%
