Answer:
h = (2 A)/(b_1 + b_2)
Step-by-step explanation:
Solve for h:
A = 1/2 h (b_1 + b_2)
A = 1/2 h (b_1 + b_2) is equivalent to 1/2 h (b_1 + b_2) = A:
1/2 h (b_1 + b_2) = A
Divide both sides by 1/2 (b_1 + b_2):
Answer: h = (2 A)/(b_1 + b_2)
1(x + 3) + 3(x - 1) = 20
1(x) + 1(3) + 3(x) - 3(1) = 20
x + 3 + 3x - 3 = 20
x + 3x + 3 - 3 = 20
4x = 20

Answer:
(x-2)2+(y-5)2=92
or
(x-2)2+(y-5)2=81
Step-by-step explanation: Center:(2,5)
The center of a circle is a point from which all points on a circle are the same distance.
Radius:9
The radius of a circle is the length of a line segment from its center to its perimeter.
The radius is typically denoted as "r" or "R".
Diameter:18
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
Circumference or (or Permieter) = 2*π*R = 2*3.14*9 = 56.5486677646163
The circumference of a circle is the distance around it.
Area:254.469004940773
Area of a Circle is the amount of space occupied by the circle.The area of a circle is p times the radius squared, which is written: A = π*R2.
The standard form for the equation oif a circle is
(x-a)2+(y-b)2=r2
And in our particular case:
(x-2)2+(y-5)2=92
(x-2)2+(y-5)2=81
The general form for the equation of a circle is
x2 + y2 + Ax + By + c = 0
We can get the general form by expanding the equation of the standard form
(x-a)2+(y-b)2=r2
(x-2)2+(y-5)2=92
(x-2)2+(y-5)2=81
x2-4x+4+y2-10y+25=81
x2+y2-4x-10y-52=0
hello!
so the difference is 101 and here is why!
you want to minus -1 from 100
100 - (-1)
but because it is a double negative it will become addition
100 + 1
so the difference is 101 feet
i hope this helped :)
