Answer: 155.5 Is your sum! (❤´艸｀❤)
Answer:
Perimeter of a SQUARE
4 x s
4 x 2.3 = 9.2 cm
Hence the perimeter of the square is 9.2cm
The answer is A
start by isolating the y variable
the rest of the work is shown here
Treat this as you would the quadratic equation x^2 - 4x - 3 + 0. Solve this by completing the square:
x^2 - 4x + 4 - 4 - 7 = 0
(x^2 - 4x + 4) = 11
(x-2)^2 = 11, and so x-2 = plus or minus sqrt(11).
Graph this, using a dashed curve (not a solid curve). Then shade the coordinate plane ABOVE the graph.
