Answer:
x²+(1/x²) = 47
Step-by-step explanation:
by identity : (a+b)² = a²+b²+2ab
(x+1/x)²= x²+(1/x)²+2(x)(1/x)
(x+1/x)²= x²+(1/x²)+2....(1)
since : (x²+1)/x = 7
(x²/x) +(1/x) = 7
x + (1/x )= 7
put the value for : x +(1/x) in (1) :
49 = x²+(1/x²)+2
x²+(1/x²) = 47
Answer:
This would be the commutative property because in either order the sum will always be the same.
You were asking about the property type, right?
I believe it is the first once because if a means the amount of apples and $1.75 is the amount paid for 1 apple, this answer would be correct.
