Answer:
7 feet
Step-by-step explanation:
We are given that:
P=54
L=13+W
With this we can substitute so that the equation looks like this:
54=2(W+13+W)
Distribute 2 to everything inside the parenthesis:
54=2W+2W+26
Simplify the equation to:
54=4W+26
Isolate 4w by -26 on each side:
28=4W
Divide both sides by 4 to isolate W:
W=7
We can fact-check this:
W=7
L=13+7=20
P=2(W+L)
54=2(7+20)
54=54
Answer: 2w
Step-by-step explanation: if the garden is shaped like a square, then all the sides are equal,
length = breadth, and the Area of a square or rectangle is the length multiplied by the breadth
and to find the length and breadth, we find the square root of the area
The area is 4w2
We know that 4 is the perfect square of 2, making 2 the square root of 4
And w2 is the square of w
This is elementary algebra, a x a = a2
b x b = b2, w x w = w2
So adding both together, the square root of 4w2 = 2w
Answer:
your mark is correct
Step-by-step explanation:
<em>The marked answer choice is correct</em>.
(2, -18) is not a global minimum, because there are function values that are lower.
(0, -6) is not a global maximum, because there are function values that are higher.
A global maximum is also a local maximum.*
_____
* More correctly, a global maximum is either a local maximum or the end point of an interval. No intervals are involved in this question.
