Genrish500 [490]

Answer:

(x + 7)^2 + (y + 3)^2 = 4

Step-by-step explanation:

The standard equation of a circle is:

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

where (h, k) is the center and r is the radius. We can substitute the information given to obtain:

(x + 7)^2 + (y + 3)^2 = 4

PYTHAGOREAN THEORM PLEASE HELP ME
madreJ [45]

Answer:

Yes.

The first has an area of 9, so each side is three.

The second has an area of 16, so each side is four.

Each side of the third square is given as 5.

So the triangle has sides of 3, 4, and 5.

3²+4²=5²

9+16=25

25=25 It works given the Pythagorean theorem.

Step-by-step explanation:

Yes.

The first has an area of 9, so each side is three.

The second has an area of 16, so each side is four.

Each side of the third square is given as 5.

So the triangle has sides of 3, 4, and 5.

3²+4²=5²

9+16=25

25=25 It works given the Pythagorean theorem.
