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!
3x-6=6(x+2)
3x-6=6x+12 3x-6x=6+12
-3x=18 X= 18/-3 X= -6 first number .
For second number you substitute x+2.
-6+2=-4
Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π
for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more
therefore answer is 36π = 113.1 inches
