Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:
Step-by-step explanation:
Take an example
14 / 20
the GCF of 14 and 20 = 2 ( 20 = 2^2 * 5 and 14 = 2*7 so 2 is the GCF)
so we can divide top and bottom of the fraction by 2 to give 7/10 = simplest form

Answer: Choice A</h3>
Angle M = Angle T, Angle G = Angle Y, Angle B = Angle T
MG = WY, GB = YT, MB = WT
The order of the letters of MGB and WYT is important.
We have M and W as the first letters of their respective sequences. So M and W pair up and they are congruent angles. Only choice A shows this. Every other answer choice has M paired with the wrong angle.
Similarly, the second letters G and Y pair up and they are congruent. So are the third letters B and T.
The segments pair up in a similar fashion. For instance, M and G are the first two letters of MGB, W and Y are the first two letters of WYT, so segment MG and WY pair up and are congruent. The other segments follow that pattern as well.
Convert the fraction to a decimal, then multiply by
