Answer: 42
Step-by-step explanation:
If they are in parentheses, you are going to multiply them, and when you multiply two negatives, you make a positive. which gives you 42.
It’s 2 because it’s crossing over the x line and has 2 lines before it
Circle equation: (x - h) + (x - k) = r²
(h, k) = center
r = radius
The center is (-7, 4)
To find the radius, take the square root of 49.
√49 = 7
The radius is 7.
Best of Luck!
