Greetings !
Given expression

write 5 as a sum



Use (a+b)³=a³+3a²b+b³ to expand the expression

Use (a+b)²=a²+2ab+b² to the second expression to expand it

Finally, simplify the expression gives

Hope it helps!
I believe that through deductive reasoning angle O is 64 degrees. The reason is it's bigger than angle R so that rules out 32 and 16 degrees, but it's not obtuse, so that rules out 128 degrees, thereby leaving you with 64. Hope this helps :)

Step-by-step explanation:
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
