If the perimeter of a square is 24 in, what is the area?(1 point)
Responses

A = 36 in^2
A = 36 in^2

A = 576 in^2
A = 576 in^2

A = 22 in^2
A = 22 in^2

A = 96 in^2
A = 96 in^2
The correct answer is: A = 36 in^2

x = 5 m<GKJ = 32 degrees
x = 5 m

x = 2 m<GKJ = 28 degrees
x = 2 m

x = 5 m<GKJ = 14 degrees
x = 5 m

x = 2 m<GKJ = 32 degrees
The correct answer is: x = 5 and m<GKJ = 32 degrees

To find the distance between two points, you can use the distance formula:

d = √[(x2 - x1)^2 + (y2 - y1)^2]

Using the coordinates of points B(-2,14) and C(3,8), the distance would be:

d = √[(3 - (-2))^2 + (8 - 14)^2]
d = √[5^2 + (-6)^2]
d = √[25 + 36]
d = √61

Rounded to the nearest tenth, the distance is approximately 7.8.

The correct answer is: 7.8

To find the coordinates of endpoint B, you can use the midpoint formula:

(x1 + x2)/2 = 6
(y1 + y2)/2 = -3

Using the coordinates of endpoint A(-1, 8) and the midpoint (6, -3), you can set up the equations:

(-1 + x2)/2 = 6
(8 + y2)/2 = -3

Solving these equations will give you the coordinates of endpoint B:

-1 + x2 = 12
8 + y2 = -6

x2 = 12 + 1
x2 = 13

y2 = -6 - 8
y2 = -14

Therefore, the coordinates of endpoint B are (13, -14).

The correct answer is: (13, -14)

To find a point E on line CD such that the ratio of segment CE to CD is 1/8, you can use the following formula:

E = C + (1/8)(D - C)

Using this formula, you can substitute the coordinates of points C and D to find the coordinates of point E.

Let's assume the coordinates of point C are (x1, y1) and the coordinates of point D are (x2, y2). Then, the coordinates of point E would be:

E = (x1, y1) + (1/8)((x2 - x1), (y2 - y1))
E = (x1, y1) + ((x2 - x1)/8, (y2 - y1)/8)

Without knowing the specific coordinates of points C and D, it is not possible to determine the exact coordinates of point E in this case.
