for problem 6, you will want to subtract both sides by 5.
n^2 + 7n + 10 = 0
then factor:
(n + 5) (n + 2) = 0
n+ 5 = 0, n +2 = 0
n = -5, n = -2
----------------------------
for problem 7, add - 12 and - 6 together
n^2 + 3n - 18
<em>(you can put </em>= 0 <em>next to the equation since that can make it easier to solve, I guess)</em>
n^2 + 3n - 18 = 0
then factor:
(n + 6) (n - 3) = 0
n + 6 = 0, n - 3 = 0
n = -6, n = 3
Answer: The missing side is 5 units.
Step-by-step explanation:
Pythagorean Theorem states that a^2+b^2=c^2. Let the hypotenuse be x.
![4^2+3^2=x^2\\16+9=x^2\\25=x^2\\\sqrt{25}=\sqrt{x^2}\\\left[\begin{array}{c}x=5\end{array}\right]](https://tex.z-dn.net/?f=4%5E2%2B3%5E2%3Dx%5E2%5C%5C16%2B9%3Dx%5E2%5C%5C25%3Dx%5E2%5C%5C%5Csqrt%7B25%7D%3D%5Csqrt%7Bx%5E2%7D%5C%5C%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%3D5%5Cend%7Barray%7D%5Cright%5D)

Answer: The y-intercept is 1
Step-by-step explanation:
On a graph, the y-intercept is the point where the line intersects the y-axis. The corresponding x-coordinate is always 0. ... When a linear equation is written in slope-intercept form (y=mx+b), the slope is represented by the variable m. It is the coefficient to x in the equation.
Answer:
q/9
Step-by-step explanation:
The quotient is an number or variable that is the product of division. My answer may be reversed or wrong, but it should be close to the correct one.
