A, B and E.

Adding and multiplying the terms allow them to keep working. However, you must make sure that each variable is changed each time. Not just one as in C and D.

consider the right triangle inside the circle with a center at point E(1,1). which equation can be used to show how he pythagore
Kruka [31]

The standard form of a circle is:

(x-h)^2+(y-k)^2=r^2

Where

(h, k) is the center

r is the radius

Since the center is (1, 1), we can write:

(x-1)^2+(y-1)^2=r^2

EG (hypotenuse of the right triangle) is the radius of the circle. Thus, we can say >>>

(x-1)^2+(y-1)^2=(LengthOfEG)^2

The correct answer is

B

the sides of a square are each multiplied by 3 to firm a new square. If the area of the original was K, then the area of the squ
Keith_Richards [23]
The area of the new square is 9k. For example if in the original square, each side was 2, then k=4. 2*3=6 so each side would be 6 long. 6*6 is 36 so the new square's area is 9 times the original.
