Answer:
x = 124
Step-by-step explanation:
Firstly yu can move the 6 to the other side...where the equation would be in this form
; fifth root of ( 249 - 2x) = 7 - 6
; fifth root of ( 249 - 2x) = 1
; 249 - 2x = 1^5
; 2x = 248...,then divide both sides by 2
; Hence..., x = 248/2
Answer:
Step-by-step explanation:
let x,x+1,x+2,x+3,x+4,x+5,x+6,x+7,x+8
be 9 integers
x+x+1+x+2+x+3+x+4+x+5+x+6+x+7+x+8=9x+36=9(x+4)
which is divisible by 9
Answer:
20
Step-by-step explanation:
f(x)=x2+3x and g(x)=2x2, find (f ∘ g)(−1)
f(x)= (-1)(2) +3 (-1)= -2+-3= -5
g(x)= 2 (-1)2= -4
(f ∘ g)= -5 x -4= 20
