Answer:
That would be a reflex angel.
Step-by-step explanation:
It' s 240 degrees.
Perimeter = 300
Area = a(w)
Width = w
Perimeter = 300 and width = w ⇒ length = [300 - 2w ]/2 = 150 - w
Area, A = width * length = w(150-w) = 150w -w^2
Roots = w = 0 and w =150
Vertex
w =[0 + 150]/2 = 75
A = 75(150-75) = 75^2 = 5625
(75,5625)
Given that the coefficient of w^2 is negative, the vertex is the maximum of the function or area.
The second coordinate of the vertex (5625) is the maximum area the fence can enclose.
Answer: the maximum area that can be enclosed by the fencing.

Answer:
X=14
Explanation:
The question tells us that the triangle is an equilateral triangle, meaning all of its side lengths are equal.
The perimeter of the triangle is all the lengths added together, so we can say this:
Perimeter=3(1.75x-2)
And since the question tells us the perimeter, we can input that into the equation as well.
67.5= 3(1.75x-2)
And now we solve:
67.5= 3(1.75x-2)
Distribute 3 into the parentheses
67.5=5.25x-6
Combine like terms (move -6 to the other side)
67.6+6=5.25x
73.6=5.25x
Divide both sides by 5.25
73.6/5.25=5.25x/5.25
14=x

Addition Answer: 1/3 + 1/4 = 4/12 + 3/12 = 7/12
Subtraction Answer: 1/3 - 1/4 = 4/12 - 3/12 = 1/12
Step-by-step explanation:
Basically, find the greatest common multiple of 3 and 4. Once you do this, then you can multiply across and solve any fraction problem!
3:7
Taxes are 30c and one dollar is 100c then the net income is 70c, making the income 30:70. this can be simplified to 3:7.
