Answer:
9 diagonals
Bit by bit clarification:
Number of Diagonals = n(n-3)/2
For instance, in a hexagon, the complete sides are 6.
Along these lines, the complete diagonals will be 6(6-3)/2 = 9.
Answer:
the sustitucion metod is easy x=5 y=3
Step-by-step explanation:
x-3y=-4 (-2)
2x-y=7 (1)
-2x+6y=8
2x-y=7
5y=15
y=3
2x-3=7
2x=10
x=5
60 matches in the year because 24+12=36+24=60 matches
If f (x) = -x + 3
Then f (-3) = -(-3) + 3
f (-3) = 3 + 3
f (-3) = 6
Hope this helps!
We have the formula: Area= width x length
And we have Area= 0.45 x 0.4= 0.18 km²= 0.18x1,000,000= 180,000 m²
That is your number
Have fun
