Miguel ordered a rectangular print for his bedroom. The print is 7/8 ft wide and 1 3/5 ft long. What is the area of the print as
Ket [755]
The answer is 1 2/5 ft²

The area (A) of the rectangle is:
A = w * l
w - width
l - length

We have:
w = 7/8 ft
l = 1 3/5 ft = 1 + 3/5 = 5/5 + 3/5 = (5 + 3)/5 = 8/5 ft

A = w * l
A = 7/8 * 8/5
A = 7/5 = (5+2)/5 = 5/5 + 2/5 = 1 + 2/5 = 1 2/5 ft²

Which equation represents a circle with a center at (2,-3) and a radius of 11
Verdich [7]

Answer:

x^2-4x+y^2+6y-108=0

Step-by-step explanation:

The- equation- of- circle- with -center- at- (h,k) -and -a -radius- of- r -is: \\(x-h)^2 +(y-k)^2 = r^2\\h = 2 , \\  k = -3\\r = 11\\(x-2)^2+(y-(-3))^2 = 11^2\\(x-2)^2+(y+3)^2 = 121\\x^2-4x+4 +y^2+6y+9 = 121\\x^2 -4x+y^2+6y+4+9=121\\x^2 -4x+y^2+6y+13=121\\x^2 -4x+y^2+6y=121-13\\x^2 -4x+y^2+6y= 108\\x^2 -4x+y^2+6y-108 = 0
