X+ 1/x =5 what is the value x²+1/x²?

1 answer:

3 0

X+ 1/x= 5
⇒ (x+ 1/x)^2= 5^2
⇒ (x+ 1/x)^2= 25
⇒ x^2+ 2(x)(1/x)+ 1/x^2= 25
⇒ (x^2+ 1/x^2)+ 2*1= 25
⇒ x^2+ 1/x^2= 25 -2
⇒ x^2+ 1/x^2= 23

The final answer is 23~

Jerry scored 581 points by collecting 7 coins. In all, how many coins does Jerry have to collect to score a total of 996 points?

Answer:

12 coins

Step-by-step explanation:

Points scored by collecting 7 coins = 581

Number of coins required to collect 996 points

Let Number of coins = c

7 coins = 581 points

c coins = 996 points

Cross multiply :

581 * c = 996 * 7

581c = 6972

Divide both sides by 581

581c / 581 = 6972 / 581

c = 12

Hence, number of coins required to collect 996 points is 12

Answer:

True, based on the Transitive Property of Equality.

Step-by-step explanation:

Note that the Transitive Property of Equality states that "If a = b, & b = c, then a = c.

In this case it is the same.

∠1 ≅ ∠2 (because both are complementary), ∠1 ≅ ∠3 (again, both are complementary), then based on the Transitive Property, ∠2 ≅ ∠3, making all of them complementary angles
