Answer: 9/25
Step-by-step explanation: 36% is equal to 0.36 which is 36/100 which can be reduced to 9/25
X = 3 or 4
explanation
x (x -3) - 4(x-3) = 0
(x - 3)(x - 4) = o
the perimeter is 68.8cm
Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4
=16 x W
then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get
Each piece of rope will be 7 meters
Answer:
sin(2x)/cos x = 2sin x*cos x/ cos x = 2 sin x = 2
sin x = 1
x = pi/2
but cos pi/2 = 0
so the given equation is indeterminate for x = pi/2
