Step-by-step explanation:

To compute x times y must use foil on the right hand side.
First: 
Outer: 
Inner: 
Last: 
------------------------------------Add like terms:

----------------


Multiply top and bottom by bottom's conjugate:

Foil the top and just do first and last of Foil for the bottom since the bottom contains multiplying conjugates:

Replace
with -1:



Answer:
actually, a and b are correct, as any line is also parallel to itself (a).
b is probably the truly wanted answer, as this line is on a chart visible as a second line and parallel to the first one.
Step-by-step explanation:
the factor of x is also the slope of the line.
for a line to be parallel to another, both need to have the same slope.
the constant number in the equation is the offset of the line from point (0,0) in y direction.
so, b is a parallel line 4 units above the first line.
Answer:
Step-by-step explanation:
Your answer would be B., because you would multiply
2.14 x 22.4 =
47.939
then you will subtract that by 42.9
47.939 - 42.9 =
5.026
