X^2 +9x +20 = x*x +5x +4x +5*4 = x(x+5) +4(x+5) = (x+4)(x+5)
hope helped
Answer:
Depends. Check out the explanation below.
Step-by-step explanation:
Depending on which number you choose, you will have the same chance for each of them. To find out the chance of each of them, you first need to find the denominator, which is 6 because there are 6 sides of a dice. Now, we need to find the numerator. How many sides are we looking at? 1? 2? 3? Depending on how many sides there are, is your probability. So, if there is one side you are trying to find, it would be 1/6. If there are two sides, it would be 2/6 or 1/3. And so on.

Answer:
The answer to your question is the letter a) √3/3
Step-by-step explanation:
Data
find tan 30°
Use the triangle 30°-60°-90° (see the picture below)
Tangent is the trigonometric function that relates the Opposite side and the adjacent side.
tan Ф = Opposite side / Adjacent side
-Substitution
tan Ф = 1/√3
or 1/√3 √3/√3 = √3/3
