N ≤ 2, if n plus 7 is less than or equal to 9 (n+7 ≤ 9) then carry the 7 over to create n ≤ 9-7 giving the answer n ≤ 2 (n less than or equal to 2)
Answer:
or 
Step-by-step explanation:
The given quadratic equation is
Group the constant terms on the right hand side.
Divide through by 5.
Add the square of half the coefficient of x., which is 
to both sides of the equation.
The left hand side is now a perfect square.
Take the square root of both sides;
or 
or 
or
The correct answer is: AB = 3.11
Explanation:
Since
--- (1)
= 50°
base = 2
And hypotenuse = AB
Plug in the values in (1):
(1) => cos(50°) = 2/AB
=> AB = 2/0.643
=> AB = 3.11
