Answer:
A
Step-by-step explanation:
(x-4)^2 = x^2 -4x -4x + (-4)*(-4)
= x^2-8x+16 as required

Answer:
answer given in step by step...
Step-by-step explanation:
13x+13(x+1)+13(x+2)=312
13x+13x+13+13x+26=312
39x+39=312
39x=312-39
39x=273
x=7
first number=13x=13*7=91
second number=13(8)=104
third number=13(9)=117
I would say c hope this helps

See below for answers
Step-by-step explanation:
Do you mean 
or 
?
Use the formula 
where 
is the amplitude, 
is the phase shift, 
is the vertical shift, and the period is 
.
Assuming your first case is true, the amplitude would be 
, your period is 
, and your midline/vertical shift is 
.
Assuming your second case is true, everything but the vertical shift stays the same. It would be 
in this case.
