If (x^2+1)/x = 7 find x^2+(1/x^2)
White raven [17]

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

The sum of two numbers is 50. The first number is 43 less than twice the second number.
Tomtit [17]
X, y - the numbers

The sum of the two numbers is 50.
x+y=50 \\&#10;x=50-y

The first number is 43 less than twice the second number.
x=2y-43 \\ \\&#10;50-y=2y-43 \\&#10;-y-2y=-43-50 \\&#10;-3y=-93 \\&#10;y=31 \\ \\&#10;x=50-y=50-31=19

The numbers are 19 and 31.

Answer:

The length of the wing is 480 centimeters

Step-by-step explanation:

2 cm on the drawing is 192 cm on the acutal wing

2 = 192

divide both sides by 2

1 = 96

since the drawing has a length of five cm, multiply both sides by 5

5 = 480

therefore, 5 cm on the drawing is equal to 480 cm on the actual wing
