10s^2-15s+20 because 5(2s^2)=10s^2, 5(-3s)=-15s, and 5(4)=20.
Answer:
A x< of 6
Step-by-step explanation:
The IQR for the data set is 17
Answer:
C= 50°+ 31°( exterior angle)
C=81°
D+45°+96°=180°(the sum of angles in a triangle)
D=180-45°-96°
D=39°
h+52°=76°( exterior angle)
h=76°-52°
h=24°
f+32°=66°( exterior angle)
f=66°-32°
f=34°
r+45°+35°=180°(the sum of angles in a triangle)
r=180-45°-35°
r=100°
n+33°=80°( exterior angle)
n=80°-33°
n=47°
