Properties:
1) a+ b = b+a Commutative
2) (a + b) + c = a + (b+c) Associative
3) a(b+c) = ab + ac Distributive
Here we are given
11 + (19 + 6) = (11 +___) + 6
The number 19 is missing on the right.
So we have
11 + (19 + 6) = (11 +19) + 6
This looks like Property 2 above.
Hence it is associative property.
The answer would be D.-13/21
Step-by-step explanation:
Since the power of x in C is 4, it is not longer linear.
Hence y = 2 + 6x⁴ is nonlinear.

Step-by-step explanation:
The surface area of a sphere is A = 4 π R² .
Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.
Circumference = π (diameter)
Divide each side by π : Diameter = circumference / π
Radius = 1/2 diameter: Radius = circumference / (2 π)
Area = 4 π R² =
4 π (circumference/2π)² =
4 π (circumference)² / 4 π²
Divide top and bottom by 4π : Area = (Circumference)² / π
Circumference = 37.68 units
Area = (37.68)² square units /π =
<em>451.93 square units</em>
