Let x and y be islands and peninsulas respectively
x+y=191919
2x+3y=454545
y = 191919- x
2x + 3 (191919 - x) = 454545
2x + 575757 - 3x = 454545
2x-3x = 454545 - 575757
-x = -121212
x = 121212
121212 + y = 191919
y = 191919 - 121212
y = 70707
Ni Hua visited 121212 islands and 70707 peninsulas
So first to find the area do 8 times 3/4 and that will give u the area.
Answer:
Days of snowfall
Step-by-step explanation:
the y- axis
Hello :
<span>g(n) = n2 − 16n + 69
=( n²-16n+64)-64 +69.....(</span><span> completing the square)
</span>g(n) = (n-8)² +5...... (<span>the vertex form)
the vertex is : (8,5)
</span><span>the axis of symmetry is the line : n = 1</span>
