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

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 = 
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
