Answer:
Step-by-step explanation:
-3=x+5
-5. -5
-8=x
Circumference = 2 x pi x radius
2 x pi x 4 = 25.13 yards
(correct to 2 decimal places)
Hope this helps!!

so notice above, the circle is centered at h,k or 0,0, the origin, and has a ratio of 5.
and y = 2, is just a horizontal line, check the picture below.
Answer:
The addition property of equality
Step-by-step explanation:
2 + 8 = 10
10 = 10
Step-by-step explanation:
our equation is x²+16x = -44
- x²+16x= -44
- x² is the first term so weill have in the middle 2*x* a number
- x²+2*x*8 = -44
- the third term is 8² wich is 64 so we will add it in both sides
- x²+2*x*8+64 = -44+64
- (x+8)² = 20
Now that we have completed the perfect square let's solve the equation
- (x+8)² = 20
- x+8 =
or x+8= -
- x = -8+
or x = -8- 
so the first answer is the correct one
64; 8 +/-
