Answer:
4x+2
Step-by-step explanation:
Perimeter = 2(width) + 2(length). So 12x+4 = 2(2x) + 2(length) .
12x+4 = 4x + 2(length) then subtract 4x from both sides to get 8x+4 = 2(length). In order to get length by itself you need to divide both side by 2.
4x+2 = length. Hope this helps!
Answer:
In the area that she observed, the water level fell 13.64mm over 6.4 years, for an average annual rate of change of: -13.64 ÷ 6.2 = -2.2 mm/ year.
1 24/25
1.96= 196/100
196/100= 49/25
49-25= 24
1 24/25
from the given equation
X+Y=20-->i
X-Y=14--->ii
add eq i and eq ii
2x=34
x=17
putting the value of x=17 in eq i
17+y=20
then y = 3 so the right answer is
17 and 3
