A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length
A(8,4.6)=(8*4.6^2)/(4tan22.5)
A(8,4.6)=42.32/tan22.5 m (exact)
A(8, 4.6)≈102.17 m^2 (to nearest hundredth of a square meter)
19x - 11 = 10x + 7
9x = 18
x = 2
19x - 11 = 19(2) - 11 = 27
3y + 27 = 180
3y = 153
y = 51
answer
x = 2 and y = 51
What language are you speaking
Step-by-step explanation:
b) y=x+1
table:
_x _|_2x_|_y_|(x, y)|
0 |2(0) |1 |(0, 1)|
1 | 2(1) |2 |(1, 2)|
2 | 2(2) |3 |(2, 3)|
3 | 2(3) |4 |(3, 4)|
c) y=3x+2
_x _|_2x_|_y_|(x, y)|
0 |2(0) |2 |(0, 2)|
1 | 2(1) |5 |(1, 5)|
2 | 2(2) |8 |(2, 8)|
3 | 2(3) |14 |(3, 14)|
To graph, plot the x, y points and connect all of them
