The distribution is very simple. Using FOIL.
It states that 
.
Also note that when multiplying expressions we multiply variables and values differently. If we have variables like 
their exponents will add. If we have values like 3 we multiply them normally.
For example your practise 3.
Now just order the expressions from bigger exponent to smaller and than values. (Usual notation although no need).
And solution is:

2s+4=5(-4-2s)
Distribute the 5
2s+4=-20-10s
add ten s to both sides
12s+4=-20
subtract 4 from both sides
12s=-24
divide by 12 on both sides
s=-2

Answer:x^3+2x^2+4x-ax^2-2ax-4a
Step-by-step explanation:
It would be 1/4 because there are 12 inches on a ruler. And if it lands between 3 and 5 there are 3 chances out of 12 that it will land between 3 and 5. 3/12 simplifies to 1/4
Answer:
(9, -4)
Step-by-step explanation:
Substitute 9 for x in the expression.
y = -(9) + 5
y = -9 + 5
y = -4
The ordered pair is (9, -4).
