Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right, so the mom would not be doing it right since addition goes first, so the answer would be 7. The dad would be right
Standard form of a circle" (x-h)²+(y-k)²=r², (h,k) being the center, r being the radius. in this case, h=-2, k=6, (x+2)²+(y-6)²=r² use the point (-2,10) to find r: (-2+2)²+(10-6)²=r², r=4 so the equation of the circle is: (x+2)²+(y-6)²=4²
