The answer would be 4. It would be 4 because 4x16=64. And 0-4x3=-12.
Answer:
-1
Step-by-step explanation:
Answer:
Where is the equation?
Step-by-step explanation:
Answer:
The sum of the interior angle is 108°
Step-by-step explanation:
To find the sum of the interior angle, you need this equation:
(The variable 
represents the number of sides does a shape have).
-Count the sides of the shape:
The following polygon shown, has 5 sides.
-After you have the number of sides of the polygon, use the number of sides for the equation and it will be written as:
-Then, you solve:
So, the sum of the interior angle is 
.
Answer:
It's like solving a quadratic, but in reverse, and in this case you'll arrive at x2+x−12=0
Explanation:
We're going to go "backwards" with this problem - normally we're asked to take a quadratic equation and find the roots. So we'll do what we normally do, but in reverse:
Let's start with the roots:
x=3, x=−4
So let's move the constants over with the x terms to have equations equal to 0:
x−3=0, x+4=0
Now we can set up the equation, as:
(x−3)(x+4)=0
We can now distribute out the 2 quantities:
x2+x−12=0
