<h3>
Answer: 39</h3>
========================================================
Explanation:
You can use the nCr formula shown below
where n = 39 and r = 1. However, you could also use the identity
which basically says there are n ways to pick 1 item if you are given a choice of n items. In this specific case, we have 39 items total, and there are 39 ways to pick one item.
The formula for the area of a square is the side squared, or multiplied together.
Basically, if the side length is x, the area is x*x or x^2.
We can use that to set up an equation.
x^2=121
x=square root of 121=11
Hope this helps!
Answer:
1
Step-by-step explanation:
Cosine = adjacent/hypotenuse
Cos A = 3/4.24
Cos B = 3/4.24
Since they are equivalent, Cos A/Cos B = 1
5/10 is rhe reduced form because 5 goes into both so 25/5=5
And 50/5=10
Answer:
x = 6
Step-by-step explanation:
Given
3x - 17 + 2x = 13 ← simplify left side
5x - 17 = 13 ( add 17 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
