Answer: -30
Step-by-step explanation: trust -3 times 5 times 2 equals -30
Answer:
Step-by-step explanation:
First, we need to write the polynomial in descending order
Then, grab the term with the highest power from the polynomial and divide it by the term with highest power from the polynomial located at the other side of the division symbol (this polynomial would be x+5)
The result (4x^2 / x) = 4x
This term will be part of the solution, and will be use to start the process of division.
This process start with the previous obtained term (4x), which will be multiplied by the polynomial from the other side of the division symbol (x+5).
The result another is another polynomial
This new polynomial will be multiply by negative 1
The new polynomial is then added to the poly (4X^2+14x-9)
The result will constitute a new poly, that will be use as the remaining of the division.
Since, our remaining differs from zero, and we still have member to simplify, we repeat the step 1 using the remaining as the new poly that needs to by divided by (x+5).
The attached picture explains the whole procedure.
In the first few steps for deriving the quadratic formula left side of the equation due to the distributive property for balancing the equation.
<h3>What is quadratic equation?</h3>
A quadratic equation is the equation in which the highest power of the variable is two.
Here, The first few steps in deriving the quadratic formula are shown in the table.
Use the substitution property of equality to solve it further,
-c=-ax² +bx
Now factor out the term a, to solve further as,
- c = a (x² + b/a x)
for half of the b value and square it to determine the constant of the perfect square trinomial as,
(b/2a)² = b²/4a²
Now the distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation.
-c + b²/4a² = a(x² + b/a x + b²/4a² )
Thus, the distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation.

Answer:
24 units
Step-by-step explanation:
Look at the coordinate plane. First start with the bottom side (LN). The line goes from -3 to 9. This means that the line is 12 units long. Now, look at the other sides. MN goes from 3 to 9, therefore, the line is 6 units long. Lastly, look at ML— -3 to 3, therefore, the line is 6 units long. Add them all up, (12+6+6) and it equals 24 units.
