Answer:

44ft

Step-by-step explanation:

The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.

Answer:

2)

2x + 6x + 8 = 32

collect like terms

8x + 8 = 32

move the constant to the right hand side and change its sign.

8x = 32 - 8

Subtract the numbers

8x = 24

Divide both sides of the equation by 8

x = 3

Which property is demonstrated by the equation (5 + a) + 3 = (a + 5) + 3?
sineoko [7]

Answer:

Communitive Property

Step-by-step explanation:

Commutative property = 2 + 3 = 3 + 2 or 2(3) = 3(2)

Associative Property = (2 x 3) 5 = 2 (3 x 5) or (2 + 3) + 5 = 2 + (3 + 5)

Inverse Property = 2 + (-2) = 0 or (2/1)(½) = 1

Basic Definitions:

<u><em>Commutative Property</em></u> - Gives you the ability to switch the order of the numbers in an expression.

<u><em>Associative Property</em></u> - Let's you move the parenthesis in an expression but not the numbers.

<u><em>Inverse</em></u> - Uses numbers like 0 and 1.

Using these basic definitions and examples, we can summarize that the best answer would be <u>Communitive Property</u>
