Answer:
is there a question or picture?
answer
D 2
factor
factor the equation 
into (x + a) and (x + b) so that a + b = -2 and a * b = -8
the two numbers that meet these conditions are a = -4 and b = 2
find solutions
set both (x - 4) and (x + 2) equal to zero to find your solutions
x - 4 = 0
x = 4
x + 2 = 0
x = -2
add solutions
since the two solutions are x = 4 and x = -2, add them together to get your final answer
4 + (-2) = 2
37.5% i believe! i’m not reallt sure if this is correct; but i believe it is. hope this helps!
Answer:
t=1
Step-by-step explanation:
16-2t = t + 9 + 4t
Combine like terms
16-2t = 9 + 5t
Add 2t to each side
16 -2t+2t = 9+5t+2t
16 = 9+7t
Subtract 9 from each side
16-9 = 9-9 +7t
7=7t
Divide each side by 7
7/7 = 7t/7
1 =t
The answer to this question is sqrt(2)/2. Invoke the unit circle to derive this expression, or use special triangles and reference triangles.
