Answer:
y = 2x + 6
Step-by-step explanation:
10x - 5y = -30
-5y = -10x - 30
y = 2x + 6
4mm
The sides of the new garden can be represented by x+9. x is the original size and 9 is the added 9mm. Multiply the sides to get (x+9)(x+9) or

this will equal the area. Create an equation to solve for the unknown original length.

Take the square root of both sides
13=x+9
Subtract both sides by 9
4=x The original side was 4mm long
Answer:
The answer is "x-h and y-k".
Step-by-step explanation:
The center is (h, k) with E (x, y) point, and its length of the legs used during extracting the standard circle equation should be found. Its right triangle length base is (x-h) units, as well as the right triangle's length, is (y-k). So, these are the required leg lengths, that's why the above-given points are correct.
