There's a bunch of them!

Commutative property of multiplication and addition means a*b = b*a and a+b =b+a

associative property means a+b+c = a+c+b = c+a+b etc. and a*b*c =a*c*b etc

distributive property of multiplication over addition means a(b+c) = a*b+a*c or an+ac

there are others

Answer:

Step-by-step explanation

4c + d

this is an expression and since they provided c and d it is easy to solve

c = 9 and d = 8. You need to plug in c and d into the expression to solve the problem.

4(9) + (8)

4 times 9 is 36 so it leaves you with 36 + 8

36 + 8 = 44

I hope this helps but basically the concept is just plugging in the numbers in place of the variables. For future problems plug in the numbers given where the variables are.

Move all terms not containing a to the right side of the equation.

29a = 11

Divide each term by 29 and simplify.
