Alright, expand the given equation:
(2+x) (2+x) (2+x) (2+x) (2+x)
Use FOIL method and distribution to solve
At the final answer, find the x^2 and the number that multiplies to it is the coefficient
I can't do the actually expansion for you, it would take a decently long time. You should be able to, its a good practice. Good luck!
Answer:
4
Step-by-step explanation:
use pythagoeron theorem
9^2-7^2=x^2
x^2=32
x=4
The answer is 10•11, if you look at the pattern, you don't have to solve the addition.
