Need ! feel free to if u know how to solve this problem! u!

Perimeter signifies the distance around the outside of a figure.  We are told that the perimeter of this figure is 42.3 m.  Add up the lengths of all the sides, including the one marked "x."  

7.8 m + x + 11.9 m + 16.3 m = 42.3 m

Combining the terms on the left:  36 + x = 42.3 (meters)

Then x = 42.3 - 36   (meters).      So, the exact value of x is    x = 6.3 meters

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
