The associative property is basically just when you move the parentheses in a problem. For example: (a+b)+c = a+(b+c).
Distributive property is a little more complicated, its better if i show you.
a(b+c) = ab+ac
so a times b plus c is the same as a times b plus a times c.
Hope i helped:)
Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.

sorry
look im trying to finish a challange u need premium if your going toask that big of a quietion my dude/dudet
Step-by-step explanation:
A coefficent is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Or in other words, the number being multiplied with the variable. For example, the 4 in 4x.
The expression is -3x + 1. If we go back to the definition, the coefficient is the number combined with the variable.
So the answer is -3.
Hope it helps!
