Answer:
10x² - 48y² - 11x + 2y - 74xy
Step-by-step explanation:
(-x+8y)+(-10x-6y)(−x+8y)+(−10x−6y)
Rearranging,
=> - x - 10 x + 8y - 6y + (-10x-6y)(−x+8y)
=> - 11x + 2y + 10x² - 48y² + 6xy - 80xy
=> 10x² - 48y² - 11x + 2y - 74xy
<h2>The above state tells only about the sum of their angle not about their areas. You are right there sum of angles is same but their areas are different. Let's take another example, rectangle also have sum of angles equal to 90 ° but it's not that rectangle is equal to circle. Square and Rectangle are equal because their areas are same.</h2>

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
Answer:

Step-by-step explanation:
I think...
54% of 400= 216
400/216= 1.85
Answer:
Part A: 140
Step-by-step explanation:
Line ACE is a straight line meaning it equals 18 degrees. To find out what Angle CEF is you have to subtract 40 from 180. That gives you 140 degrees.
