raketka [301]
X=number of games played

just do simple multiplication

remember that orded pairs are (x,y)

x=5
y=0.50(5)+3
y=2.5+3
y=5.5
orderd pair is (5,5.5)


x=10
y=0.50(10)+3
y=5+3
y=8
ordered pair is (10,8)


x=20
y=0.50(20)+3
y=10+3
y=13
ordered pair is (20,13)



(5,5.5)
(10,8)
(20,13)

Given: quadrilateral MNOL with MN ≅ LO and ML ≅ NO
mr_godi [17]
The answers are ONM, NOM, and alternate interior angles.
Based on the SSS postulate, the two triangles △MLO and △ONM are congruent since three sides of △MLO are respectively equal to the three sides of △ONM.
Based on CPCTC, all of the corresponding angles of △MLO and △ONM are congruent as well since the two triangles are congruent, that is,   
     ∠LMO≅∠NOM and ∠NMO≅∠LOM.
Since the pair ∠LMO and ∠NOM as well as ∠NMO and ∠LOM are angles on the inner side of two lines but on opposite sides of the transversal MO, these pairs of angles are also alternate interior angles.

Answers:

5) product is 35ax^2 - 42axy + 7y^2

6) product is -a^6b^2 - 8a^5b - 5a^4

7) product is 12x^5y + 6x^4y^2 + 21x^3y^3

8) product is 3x^3y^2 - 6x^3y + 3x^5y - 3x^4y

9) product is x^{3n} + 7x^{n+1} - 3x^n

=============================================

Explanation:

For each of these questions, you'll multiply the term outside by each term inside the parenthesis. I'm using the distributive property.

In problem 5, we multiply the outer 7a by the following terms inside like so

7a(5x^2-2xy+y^2-4xy)\\\\7a(5x^2-6xy+y^2)\\\\7a(5x^2)+7a(-6xy)+7a(y^2)\\\\35ax^2-42axy+7ay^2\\\\

The other problems will have similar steps.

--------

A useful rule to keep in mind is that a^b*a^c = a^{b+c}

For example, x^2*x^3 = x^{2+3} = x^5
