Answer:

cot²x

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1, then

1 - sin²x = cos²x

1 - cos²x = sin²x

Thus

$\frac{1-sin^2x}{1-cos^2x}$ = $\frac{cos^2x}{sin^2x}$ = cot²x

(11k^4 - 4m) + (-2k^4 - 15m)
Add -2k^4 to 11k^4. This would be the same as subtracting 2k^4 from 11k^4
9k^4 - 4m - 15m
Add -15m to -4m. This would be the same as subtracting 15m from -4m
Final Answer: 9k^4 - 19m

the length of a rectangle is 4 cm more than the width and the perimeter is at least 48cm. what are the smallest possible dimensi

wel

X=length
x+4=width
$2(x+4)+2x=48$
$2x+8+2x=48$
$4x=40$
$x=10$
It means that length will be equal 10 and width 14 :)
so dimensions of this rectangle is 10x14 :)
