38.5 = x
Step-by-step explanation:
9/ (x+2) = 2/9
Using cross products
9*9= 2(x+2)
Distribute
81 = 2x+4
Subtract 4 from each side
81-4 = 2x+4-4
77= 2x
Divide each side by 2
77/2 = 2x/2
38.5 = x
Answer:
B. 21.1 yd
Step-by-step explanation:
The perimeter of the figure is the sum of all its three sides.
Take note that the dotted line is not a side length of the figure.
The side lengths are 9 yd, 5 yd, and 7.1 yd.
Therefore, the perimeter of the figure = 9 + 5 + 7.1
Perimeter = 21.1 yd.
Also, take note of the unit of the perimeter. Unit of the perimeter would not be squared. Only area has a unit that is squarred.
