Answer:
The dimension that maximizes area is 144ft by 144ft
Step-by-step explanation:
Given
-- perimeter
Required
The dimension that gives maximum area
Perimeter is calculated as:
So, we have:
Divide through by 2
Make L the subject
Area is calculated as:
Substitute
Open bracket
Differentiate A with respect to W
Set to 0 to calculate W
Collect like terms
Divide by 2
Recall that:
Let x be the number.
Then:
(x)+(x+1)+(x+2)>102
(x)+(x+1)+(x+2)<109
x+x+1+x+2
3x+3>102
3x>102-3
3x>99
x>22
3x+3<109
3x<109-3
3x<106
x<35.33
Therefore, the number can be bigger than 22 but less than 35.333 to meet the requirements.
Hope I helped :)
-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy
—> -6x2(expo) - 28y2(expo) + 26xy
Check the answer again just to be sure, it’s been a while since I’ve had algebra!
