Find the other angles then take the two angles of one triangle and take it away from 180. All the angles in an triangle add up to 180 degrees.
Step-by-step explanation:
OK so your gonna add 6 and 11 then multiply it by 3, the height. then your gonna divide by 2
(2x-1)^7
=(2x)^7+7(2x)^6(-1)+21(2x)^5(-1)^2+35(2x)^4(-1)^3+35(2x)^3(-1)^4+21(2x)(-1)^5+7(2x)(-1)^6+(-1)^7
=128x^7+7(64x^6)(-1)+21(32x^5)+35(16x^4)(-1)+35(8x^3)+21(4x^2)(-1)+14x-1
=128x^7-7(64x^6)+672x^5-35(16x^4)+280x^3-21(4x^2)+14x-1
=128x^7-448x^6+672x^5-560x^4+280x^3-84x^2+14x-1
The coefficient of x^2 is -84
Answer:
12.5
Step-by-step explanation:
Dividing 100/8, we find that there is a 12.5% chance of any colored marble being picked.
Good luck! Hope this helps!
