Answer:
16
Step-by-step explanation:
Given the equation,
, let's solve for x as follows,
Subtract 200 from both sides


Subtract 15x from both sides


Divide both sides by -5

First of all Horner
First we try with -3
1. 2. -5. -6.
-3. 3. 6
1. -1. -2. 0
To verify: -3^3+2*-3^2+15-6=0
Now we have this equation
(X+3)*(x^2 - x -2)=0
I dont know If you know sum and product but that is the easiest way so sum= 1 product = 2 so 2 and -1 are the answers.
You can do this too by this way : b^2-4ac= D
X= (-b(+or-)d^1/2)/2a
So all the zeros
2, -1 and -3

Answer:

Step-by-step explanation:
The slope-intercept form of the equation of a line:

m - slope
b - y-intercept → (0, b)
The point-slope form of the equation of a line:

m - slope
(x₁, y₁) - point
We have the equation of a line:

and the point (0, 2) → b = 2.
Substitute:

15 inches because u have to use the Pythagoras formula which is a^2+b^2=c^2 Which is 9^2+12^2=225
Then the square root of 225= 15
