# Need help on following problems, have tried to work them out and am confused..

#12 (Commutative & Associative Properties)

-8 + 12 - 9 - 15 + 6 - 22 + 3

#34 (Distributive Property)

Use distributive property to write each sum or difference as a product.

7b - 49

#54 Multiplication Property of Zero

x * 5 = 5x

#26 (Using the Properties in Computation)

Perform each computation. Make use of appropriate rules to simplify each problem

33 * 2 - 12 * 33

#38 (Combining like terms)

-19m - (-3m)

#100 Simplify each expression

2(xsubscript 2 - 3)-(6xsubscript 2 - 2) + 2(-7xsubscript 2 - 4)

#36 (Add and Sub of polynomials)

(2x - 5) - (xsuscript2 - 3x + 2)

#42 Perform and indicate operations vertically

Subtract

-3xsubscript 2 + 5x - 2

xsubscript 2 - 5x - 6

#56 Multiplication of polynomials

(xsubscript2 - 3x + 2)(x - 4)

#92 Perform the indicated operations. A variable used in an exponent represents and integer; a variable used as a base represents a nonzero real number.

(bsubscript3z - 6) -(4bsubscript3z - 7)

#24 The FOIL method--find each product.

(7a - 2x)(x + a)

#34 The Square of a Binomial. Find the square of each sum or difference

(3w - 2x)subscript2

#44 Product of a sum and a difference

(3 + 5x)(3 - 5x)

NOTE WHERE I HAVE TYPED IN SUBSCRIPT AND THE NUMBER, I DID THAT BECAUSE I DONT KNOW HOW TO MAKE THE NUMBER SMALL TO SHOW HOW IT IS WRITTEN IN MY PROBLEM. THANK YOU FOR ALL YOUR HELP.
