Hi there!

Use the chain rule:
f(g(x)) = f'(g(x)) · g'(x)
Thus:
dy/dx sin(x) = cos(x)
dy/dx cos(x) = -sin(x)
Use the chain rule format:
f(x) = sin(x)
g(x) = cos(x)
cos(cos(x)) · (-sin(x))
-sin(x)cos(cos(x))
21. 2•2=4
24. 3.4•2.4=5.8
27. -1.6•3.6=-5.76
30. 3/1.4=2.1
Hope this helps!
Answer: perimeter = 302m
area = 5544m^2
Step-by-step explanation:
perimeter = 2(l + b)
= 2(63 + 88)
= 2 x 151
= 302 m
Area = l x b
= 88 x 63
= 5544 m^2
Hope it helped u,
pls mark as the brainliest

To find these two lets convert this into slope-intercept form:
-7x + 7y = -17
7y = 7x -17
y = x - 17/7
So, the slope is 1 and the y-intercept is -17/7
Hope this helps!
