Mathematics
1 answer:
Hunter-Best [27]3 years ago
5 0

Answer:

x = ±sqrt(y-11)

Step-by-step explanation:

y = x^2 +11

Subtract 11 from each side

y -11 = x^2 +11-11

y-11 = x^2

Take the square root of each side

±sqrt(y-11) = sqrt(x^2)

±sqrt(y-11) = x

The hypotenuse of a right triangle is 8 cm longer than the longer leg. The shorter leg is 17 cm shorter than the longer leg. Fin
balu736 [363]

Answer:

  45 cm

Step-by-step explanation:

Let x represent the length of the longer leg. Then the hypotenuse is x+8 and the shorter leg is x-17. The Pythagorean theorem gives the relation between these values as ...

  (x +8)^2 = x^2 +(x -17)^2

  x^2 +16x +64 = 2x^2 -34x +289 . . . . eliminate parentheses

  0 = x^2 -50x +225 . . . . . put in standard form

  0 = (x -45)(x -5) . . . . . . . . factor

Solutions to this equation are x=5 and x=45. The value of x must be greater than 17, so the useful solution is x=45.

The length of the longer leg of the triangle is 45 cm.
