Answer:
(n-2) × 180°
Step-by-step explanation:
Sum of interior angles for a polygon = (n-2) × 180°
---------
you have found is yourself!
Answer:
put x=-1, and the rest will be easy
Since 980÷2=490÷2=245÷5=49÷7=7÷7=1
980=2×2×5×7×7
the greatest perfect square will be
7*2*7*2
14*14=196
The answer would be graph b.
It would be graph b because the point would be five to the left(West) and two down(South).
Answer:
y=8x-69
Step-by-step explanation:
you would use the equation y-y1 = m (x - x1)
plug in m = 8 , y1 = 3, x1 = 9
now you have y - 3 = 8 (x-9)
distribute 8 --> y-3 = 8x - 72
add three to both sides to get y = 8x - 69
