It's an octagon.
The sum of the measures of the angles in the polygon with n sides:
S = 180°(n - 2)
n = 8
S = 180°(8 - 2) = 180° · 6 = 1080°
Answer: 1080°
The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0.
Tacking on "-8" to |x+5| leads to |x+5|-8
The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|
Final Answer: choice C)
Answer:
D
but not sure because I'm not that good
Answer:
Step-by-step explanation:
let 25 % copper=x kg
75 % copper=(100-x) kg
0.25 x+(100-x)*0.75=100*0.61
25x+7500-75 x=6100
-50 x=-1400
50 x=1400
5x=140
x=28
25 % of Copper=28 kg
75 % of Copper=100-28=72 kg
