Answer:
When raising an expression of that format to any power, after grouping like terms, you'll always find that the odd numbered terms are positive, and the even numbered terms are negative.
For example:
(x - y)² = x² − 2xy + y²
(x - y)³ = x³ − 3x²y + 3xy² − y³
(x - y)⁴ =x⁴ − 4x³y + 6x²y² − 4xy³ + y⁴
etc.
B.
X=5
7(5+9)=7•x+7•9
(7•5)+(7•9)=7x+63
35+63=7x+63
Subtract 63 from both sides and you will be left with
35=7x
Divide each side by 7 (you pretty much just divide 35 by 7)
And x=5
