Answer:
A, the first option, 49 square cm
Step-by-step explanation:
[] To know
-> A squares sides are all the same size
-> The area of a square can be found by finding L * W
[] Solving
-> We can use the points given to solve for one side, EF, of the square
-> Both the x coordinates are the same, so we can subtract the y values as they are on the same line.
6 - -1 = 6 + 1 = 7
-> Now for the area
7 * 7 = 49 square cm

Answer:
Step-by-step explanation:
Plug x for y and y for x.
y = 2x^2 + 2
x = 2y^2 + 2
Then isolate the y variable.
x - 2 = 2y^2
sqrt(x - 2) = 2y
(sqrt(x - 2))/2 = y
Answer:
(-2, -3)
Step-by-step explanation:
90° clockwise rotation:
(x, y) -----> (y, -x)
Let's apply this to our coordinates:
(x, y) -----> (y, -x)
(3, -2) -----> (-2, -3)
Simply make the old y-coordinate the new x-coordinate, and make the old x-coordinate negative and make the new y-coordinate.
Therefore, the coordinate of the new point is (-2, -3).
Answer:
<h2>x = 1 and y = -6 → (1, -6)</h2>
