Answer:
Remember, the expansion of
.
Then,

a) since
, then
. Therefore, the coefficient of
is 
b)
. Then k=5 and the coefficient of the term is 
c)
, then k=4 and the coefficient of the term is 
you would multiply 10 x -12 by distributing the 10 into the parenthesis.
The answer would be negative because a postive times a negative is a negative.
The answer is -120
Answer:
<h2>2</h2>
Step-by-step explanation:
<h3>Let n= 4, m= -2 and j= 5</h3><h3 /><h3>(9n + 8m)/2j</h3><h3>= 9(4) + 8(-2)/2(5)</h3><h3>= 36 + (-16)/10</h3><h3>= 20/10</h3><h3>= 2</h3><h3 />
No, u cant
a^2 + b^2 = c^2.....pythagorean theorem used on only right triangles...where a and b are the legs and c is the hypotenuse
a^2 + b^2 = 23^2
a^2 + b^2 = 529...so u would have to find 2 square numbers that add up to 529. There aren't any.
