Answer:
x^2 +2x +1
Step-by-step explanation:
(x+1)^2
=(x+1)(x+1)
= x×x+x×1+1×x+1×1
=x^2+x+x+1
=x^2+2x+1
Answer: 13/20
Step-by-step explanation:
Recall that 60 minutes = 1 hour
So, 39 minutes = Z hour (Let the unknown hour be Z)
Then to get the value of Z,cross multiply
Z x 60 = 39 x 1
60Z = 39
Divide both sides by Z
60Z/60 = 39/60
Z = 39/60
Let 3 divide through 39 and 60
So, Z = 13/20
Thus, 13/20 of an hour is 39 minutes
