Answer:
C = 16
Step-by-step explanation:
Substitute r = 8 into the equation for C, hence
C = 2r = 2 × 8 = 16
C=16
If I cunderstand your question I think the equation is
If we sub 8 in for r, we get
w = p(y - z)
divide p on both sides
Subtract y on both sides
Divide -1 on both sides
i think the second one
i think it would be the smartest thing to pick
10
one interior angle in a pentagon is 108^o.
5 interior angles are 540^o.
If we add 12+7+16+9+10, we get 54x=540^o
That means x=10
5) arccos A = 28°
6) arcsin A = 53°
5) cos A = 30/34
6) sin A = 32/40
2x^2+14x+5
x^2+9x+5x+5
Combine Like Terms:
=2x^2+9x+5x+5
=(2x^2)+(9x+5x)+(5)
=2x^2+14x+5
