If x+1/x=5 then find the value of (x^2+1/x^2) is?
Degger [83]

Recall that

(a+b)^2=a^2+2ab+b^2

So we have

\left(x+\dfrac1x\right)^2=x^2+2+\dfrac1{x^2}

Given that x+\frac1x=5, we get

x^2+\dfrac1{x^2}=5^2-2=\boxed{23}

ASAP!! Three consecutive numbers have a sum of 156. What are the 3 numbers?
ryzh [129]

For this problem, all you need to do is find the three #'s that add up to 156.

So, lets look at the answers and add them up.

A. 50, 52, 54

50 + 52 + 54 = 156

B. 51,52,53

51 + 52 + 53 = 156

C. 49,50,51

49 + 50 + 51 = 150

D. 49,51,53

49 + 51 + 53 = 153

We get the answers (50,52,54) and (51,52,53)

Now, consecutive numbers are numbers that in order, like 1,2,3.

Therefore, the answer is (51,52,53)
