(f+g) (n) = (–5n +1 ) + (- 6n +2) = –11n +3
(f+g) (n) = –11n +3
(f+g) (–2) = – 11 (–2) +3 = 22 +3 = 25

Answer:
Step-by-step explanation:
(x2 - y2)2 + (2xy)2 = (x2 + y2)2
1. Let x = 2 and y = 1 .
2. x must be greater than y
- as the sides of a triangle must be positive.
We can enter any positive integer values for x and y as long as x > y because we are dealing with an identity.
3. Then substituting, we have
(2^2 - 1^2)^2 + (2*2*1)^2 = (2^2 + 1^2)^2
3^2 + 4^2 = 5^2
9 + 16 = 25
25=25
So the triple is 3,4 and 5.
4. At least one leg must be even because one term (2xy) must be even - multiplying by 2 always gives an even value.
width: x/2, Length:x
18=x(x/2), 18=x^2/2, 36 = x^2, x= -6,6 Use the positive value of 6 for x. the width will be 6/2=3.
