Answer:
t = 10.9
Step-by-step explanation:
9.3-t=-1.6
Subtract 9.3 from each side
9.3-t-9.3=-1.6-9.3
-t =-10.9
Multiply each side by -1 to find t
t = 10.9
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 +/-
