We can draw a square with given side many ways. Square means the sides are equal in length. The diagonals are equal and bisect each other in mutually perpendicular.One method is first we draw a line segment equal to AB. The end points are marked as A and B. From these points draw a perpendicular, using scale or compass mark the points on this perpendicular equal to AB. these points be C and D. Join these point C and D get CD. Now the square is ready. ABCD is the square.

Answer:

y = -1, x = -2

Step-by-step explanation:

First, multiply the top equation by 2 to make 3x become 6x:

6x - 8y = -4

Second, multiply the bottom equation by 3 to make -2x become -6x:

9y - 6x = 3

Add the two equations together, and you get:

y = -1

Plug in y as -1 into the first or second equation:

3x - 4(-1) = -2

3(-1) - 2x = 1

x = -2

Answer:

Step-by-step explanation:

We see that we can factor out 2x from the equation! So our equation becomes 2x(x-2) = 0.

Since the only way for things to multiply to equal to zero is if at least one of the numbers is 0.

So if x-2 is the 0, then x = 2.

If 2x is the 0, then x = 0.

So our answer is C. 0,2
