Hai! So, I have all the math and explanations in the picture attached.
I forgot to add on there(and you'll see it) wen i subtract 3x and add 10 to the other side it cancels each other out. -3 + 3= 0 and -10 + 10 = 0. Etc.
Other than that, if you have any other questions, comment them down below. :)
The area formula is length times width, and since the length is 17 cm in this case, 17 times width = 102, so we must divide 102 divided by 17, and you will get 6. The perimeter formula is 2 times the length plus 2 times the width, so
2(17) + 2(6), which gives us 46, so the perimiter is 46.
Yes it is. Ax+By=C is standard form. :)

Answer:
(a) The critical points of f are x=0 and x=3.
(b)f is decreasing on 
and f is decreasing on 
.
(c) Therefore the local minimum of f is at x=3
Step-by-step explanation:
Given function is
(a)
To find the critical point set f'(x)=0
The critical points of f are 0,3.
(b)
The interval are and .
To find the increasing or decreasing, taking two points one point from the interval (0,3) and another point .
Assume 1 and 4.
Now 
and 
Since 1∈ , f'(x)<0 and 4∈ , f'(x)>0
∴f is decreasing on and f is decreasing on .
(c)
Differentiating with respect to x
Now
and
Since f''(x)>0 at x=3
Therefore the local minimum of f is at x=3
