When you match the pattern of (x+y)⁴ to (a+b)ⁿ, you see that a=x, n=4. Then the first term aⁿ can be found by substituting these values for "a" and "n":
... x⁴
Positive 3, If You're starting at -6 and you add the first 6 it's at 0, now you have 3 more to add to make 9. And that gives you positive 3. or if you do 9 - 6 you can get your answer that way too.
3/5x+22=28 (Simplify, get all the whole numbers on one side)
-22 -22
5(3/5x)=(6)5 (Get rid of the fraction by multiplying everything by 5)
3x=30 (Get the variable by itself, divide by 3)
x=10
Square x first then add x then subtract by 2
Answer:
