Answer:
0.4
Step-by-step explanation:
1.would be a right triangle because that little square and the lines connected to it form a right angle
You just have to figure it where you can place 2 solid lines and get 10 triangles ( i can only get 9). Think about the pentagon in the middle of the triangles and see if somehow you can create more triangles using only the two straight lines.
Answer:
W = 7 - x
Step-by-step explanation:
The perimeter is P= 2L + 2×W , where L is the length and W is the width.
If L = (x+2) , replacing L with the expression x+2 we have
P= 2×(X+2) + 2W ⇔ 18 = 2x + 4 + 2W ⇔ 2W =18 - 2x - 4 ⇔ 2W = 14 - 2x
⇔ W = 7 - x
The area of a square is its length times its width: l x w = 361
Since the length of a square is the same as its width, replace 'w' with 'l': l x l = 361
l x l = l² = 361 ---> l = √361 ---> l = √361 ---> l = 19 ft.
