Answer:
n + y
Step-by-step explanation:
a² - b² = (a +b)(a - b)
÷ 
{ (n + y) in the denominator and numerator will be cancelled ;
(n - y) in the denominator and numerator will be cancelled
= n + y
Add 11 to each side. X = 90+11
X = 101

Answer:
(B) Parallel to x-axis
Step-by-step explanation:
y = 7
This is a constant line, in which the value of y is always of 7, no matter the value of x.
In a line in which the value of y is constant, this line is parallel to the x-axis, so the correct answer to this question is given by option b.
