Answer:
D
Step-by-step explanation:
Answer:
Step-by-step explanation:
We see that the two terms share an x, so we can pull that out:
Now notice that we have a difference of squares (
). Given a difference of squares, 
, this can always be factored into 
. We can use this in this case: 
.
So, our final factorized form is: .
Hope this helps!
-22 = -2x + 9
-31 = -2x
-31/-2 = x
x = 15.5
Answer:
9°
Step-by-step explanation:
In a ∆, equal sides make equal angle to the third side. So the angle that's not mentioned is same '2'.
Sum of angles in a ∆ = 180°
80° + m/_2 + m/_2 = 180°
80° + (5x + 5) + (5x + 5) = 180°
10x + 90° = 180°
10x = 90°
x = 9°
Answer: 1.601 × 10^-1
Step-by-step explanation: 1 minute = 60 seconds or 1 second = 1/60 minutes
9.63 seconds = 9.63/60 minutes
9.63/60 = 963/6x1000 = 321/2x1000
=160.1/1000=1.601/10 = 1.601 x 10^-1 minutes :)
