Answer: x=-10
Step-by-step explanation: hope this help
It depends on what its asking for and what dimension it is. If its 2D, the area is lengthXwidth, and perimeter you would add all the side lengths. If its 3D, volume is lengthXwidthXheigth.
Answer:
In interval form range is [-2,16]
Step-by-step explanation:
Here we can see that given equation is circle
whose center is (5,7 ) and radius is 8 ,
Range of the circle is actually values of y it changes from
if (h,k) is the center and r is the radius of circle then range is given by
k-r ≤y ≤ k+r
here in the question k = 7 and r =9
therefore range is
7-9 ≤y ≤ 7+9
-2 ≤y ≤ 16
In interval form [-2,16]
