|x|=6

i don't know what the answer would be

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

Me! i really need to get this right before 9. prove the divisibility of 7^6+7^5-7^4 by 11. use factoring so you get a number times 11. just tell me the number. i need this done asap

Aquadratic equation in standard from is written ax^2= bx+c, where a, b and c are real numbers and a is not zero?
