(n + 7)2 = n - 1
2n +14 = n - 1
2n - n +14 = n - n - 1
n + 14 -14 = -1 - 14
n = -15 
(-15 + 7)2 = -15 - 1
(-8)2 = -16
-16 = -16

The Canadian goose flew for 4 hours and the Great blue heron flew for 10 hours
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let a represent the time flown by the goose and b represent the time flown by the heron. Hence:
a + b = 14    (1)
Also:
20a + 10b = 180   (2)
From equation 1 and 2: 
a = 4, b = 10
The Canadian goose flew for 4 hours and the Great blue heron flew for 10 hours

Step-by-step explanation:
3a^2+24a+45=0
×3/3( first ×3)
9a^2+24(3a)+135=0
(3a+15)(3a+9)=0
now /3
3(a+5)(a+3)
a=-5✓
a=-3✓
