I think... J because 
x + 1 / x^3 - x
Factor out x from the expression 
x + 1 / xx(x^2 - 1) 
Use a^2 - b^2 = (a - b)(a + b) to factor the expression 
x + 1 / x • (x - 1) • (x + 1)
Reduce the fraction with x+ 1
1 / x • (x - 1)
Distribute x through the parentheses 
1 / x^2 - x

X(-x^4)(-x^4)=
The answer is x^9
        
             
        
        
        
The answer to your question should be "<span>Both weight and mass are used equally by scientists"</span>
        
             
        
        
        
Answer:
hey,its option a
Step-by-step explanation:
because angle F= angle M and angle G= angle L
and angle H= angle N
To know third angle in ∆HGF
,we know sum of all angles in a triangle is 180°
______________________________
let angle H be unknown value x
x+51+36=180
x=180-87 ---------------- 1
similarly in ∆MNL
let angle be y 
51+36+y=180
y=180-87----------------2
_______________________________
From 1&2 we observe qngle x= angle y
