Step-by-step explanation:
our equation is x²+16x = -44
- x²+16x= -44
- x² is the first term so weill have in the middle 2*x* a number
- x²+2*x*8 = -44
- the third term is 8² wich is 64 so we will add it in both sides
- x²+2*x*8+64 = -44+64
- (x+8)² = 20
Now that we have completed the perfect square let's solve the equation
- (x+8)² = 20
- x+8 =
or x+8= -
- x = -8+
or x = -8- 
so the first answer is the correct one
64; 8 +/- 
Answer:
In this question if g and h is constant then;
111 = 14g
14g = 111
g = 111/14
g = 27.7 ~ 28
And also,
13.65 = h + 4.88
h + 4.88 = 13.65
h = 13.65 - 4.88
h = 8.77
