How do you solve for x in x^2+5x=36

Answer: (-9,4)

Step-by-step explanation: First, we set the equation equal to zero by subtracting 36 from both sides to get x² + 5x - 36 = 0.

Next, we factor the left side of the equation

as the product of two binomials.

Since the factors of -36 that add to +5 are +9 and -4,

we have (x + 9)(x - 4) = 0.

This means that either x + 9 = 0 or x - 4 = 0.

Solving each equation from here,

we have x = -9 or x = +4.

So your solution set is (-9,4).

First we want to set the equation equal to zero by subtracting 36 from each side...

x^2 + 5x -36 = 0

Now we factor

(x + 9)(x - 4) = 0

Now set each expression equal to zero and solve...

x + 9 = 0              x - 4 = 0
x = -9                    x = 4

Your solution set is

(-9, 4)

A figure is a quadrilateral if and only if it is a polygon; biconditional true or false
Afina-wow [57]
I think the correct answer is false. A figure is not only a quadrilateral if and only if it is a polygon. A polygon can have three or more sides. A<span> </span>polygon <span>is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit</span>

  • <em>Answer:</em>

<em>25</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there !</em>

<em>6×7 - 3²×9 + 4³ =</em>

<em>   1. raise the numbers to power</em>

<em>= 6×7 - 9×9 + 64</em>

<em>   2. we perform the multiplications</em>

<em>= 42 - 81 + 64</em>

<em>   3.  we perform addition and subtraction</em>

<em>= (42 + 64) - 81</em>

<em>= 106 - 81</em>

<em>= 25</em>

<em>Good luck !</em>
