Answer:
-(7y^3+7y+36)
Step-by-step explanation:
(-73-y+1)+(-7y^3-6y)
-37+1-y-7y^3-6y
-36-y-6y-7y^3
-36-7y-7y^3
-7y^3-7y-36
-(7y^3+7y+36)
First you had to add by seven from both sides of equation form.

Then simplify by equation.

Next, you multiply by two from both sides of equation form.

And finally, simplify by equation.





Final answer:

Because they are in the center.
Answer:
- ength (l) : (10-2*5/3) = 20/3
- width(w): (10 - 2*5/3) = 20/3
- height(h): 5/3
Step-by-step explanation:
Let x is the side of identical squares
By cutting out identical squares from each corner and bending up the resulting flaps, the dimension are:
- length (l) : (10-2x)
- width(w): (10-2x)
- height(h): x
The volume will be:
V = (10-2x) (10-2x) x
<=> V = (10x-2
) (10-2x)
<=> V = 100x -20
- 20
+ 4
<=> V = 4
- 40
+ 100x
To determine the dimensions of the largest box that can be made, we need to use the derivative and and set it to zero for the maximum volume
dV/dx = 12
-80x + 100
<=> 12
-80x + 100 =0
<=> x = 5 or x= 5/3
You know 'x' cannot be 5 , because if we cut 5 inch squares out of the original square, the length and the width will be 0. So we take x = 5/3
=>
- length (l) : (10-2*5/3) = 20/3
- width(w): (10 - 2*5/3) = 20/3
- height(h): 5/3
Answer:
Step-by-step explanation:
So for this we have to find the percentage by using 'percentage of error'
If at first it was 15 then it went up to 19 we have to subtract 15 - 19= -4
Ignore the negative. Now divide= 4/19= 0.21
The size went up by 21%
