Hello!
A trinomial is a expression consisting of three different terms
To turn this into a trinomial we multiply everything to each other
<u> 3x </u>
3x * x = 
3x * 10 = 30x
<u> 8 </u>
8 * x = 8x
8 * 10 = 80
Now we put them all together in an equation

Combine like terms

The answer is

Answer:
28.3 cm
Step-by-step explanation:
The formula to find the circumference is 2•π•radius. The diameter is 9 cm, so the radius is 9/2 = 4.5 cm. So, the circumference is:
2•4.5•3.14 = 28.26 ≈ 28.3 cm
The sequence is arithmetic since the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
=
a(n) = 15+(n-1)-4
