Select all of the following that are quadratic equations. 7x2 + 14x = 0 x3 - 3x2 + 1 = 0 5x - 7 = 0 x2 + 3x -5 = 0 x - 5 = 9x +
Tpy6a [65]

Answer:

7x2 + 14x = 0

x2 + 3x -5 = 0

x2 - x = 3x + 7  

Step-by-step explanation:

A quadratic equation has the highest power of x to the second power.  It must have x to the second power

7x2 + 14x = 0  quadratic

x3 - 3x2 + 1 = 0   not quadratic  but cubic

5x - 7 = 0  not quadratic  but linear

x2 + 3x -5 = 0   quadratic

x - 5 = 9x + 7  not quadratic but linear

x2 - x = 3x + 7  quadratic

If you place a 50-foot ladder against the top of a 14-foot building, how many feet will the bottom of the ladder be from the bot
tia_tia [17]

Answer:

The measure of bottom of ladder from bottom of building is 48 .

Step-by-step explanation:

Given as :

The length of the ladder = l =  50 foot

The height of the building = h = 14 foot

Let The measure of bottom of ladder from bottom of building = x foot

Now from figure

<u>The figure is of right angled triangle</u>

So,

Hypotenuse² = perpendicular² + base²

Or, OB² = AB² + OA²

Or, OA² = OB² - AB²

Or,  x² = (50)² - (14)²

Or,  x² = 2500 - 196

Or,  x² = 2304

∴  x = \sqrt{2304}

I.e x = 48

So,The measure of bottom of ladder from bottom of building = x = OA = 48 foot  .

Hence, The measure of bottom of ladder from bottom of building is 48 . Answer
