Answer:

  1

Step-by-step explanation:

You "complete the square" by adding the square of half the x-term coefficient. Here, that is ...

 ((-2)/2)² = 1 . . . . value added to complete the square

If you want to keep 0 on the right, you must also subtract this value:

  x² -2x -36 = 0

  x² -2x +1 -36 -1 = 0 . . . . . . add and subtract 1 on the left

  (x -1)² -37 = 0 . . . . . . . . . . . written as a square

In the figure below, find the exact value of y. (Do not approximate your answer.)
e-lub [12.9K]

The exact value of the y in the similar right triangle is 2.2360679775 units

<h3 /><h3>How to find the side of a triangle?</h3>

The triangles are similar.

Similar triangles have corresponding sides of equal ratio.

The corresponding angles of similar triangle are equal.

Therefore, using similar ratio,

y / 5 = 1 / y

cross multiply

y × y = 5 × 1

y² = 5

square root both sides

y = √5

Therefore,

y = 2.2360679775 units

Q is the midpoint of line segment PR. PR=9x-31 and QR=43 ; find x
bulgar [2K]

notice that, if Q is the midpoint of PR, that simply means that PQ = QR = 43.


\bf \boxed{P}\underset{\leftarrow 9x-31 \to }{\stackrel{\stackrel{\downarrow }{43}}{\rule[0.35em]{10em}{0.25pt}}Q\stackrel{43}{\rule[0.35em]{10em}{0.25pt}}}\boxed{R}&#10;\\\\\\&#10;9x-31=43+43\implies 9x-31=86\implies 9x=117&#10;\\\\\\&#10;x=\cfrac{117}{9}\implies x=13
