Answer:
x = 5
Step-by-step explanation:
Also in this case we can use the Pythagorean theorem in this way
x^2 + (5√3)^2 = 10^2
x^2 + 75 = 100
x^2 = 25
x = +/- 5
we take only the positive value because a lenght can’t be negative
x = 5
That would be A. because 75*74 because he had 75 students to pick the first time and 74 to pick the second student. So in short the answer is A.
If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.
If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.
So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
Yes, it is. if you end up getting 4.85239854285696357835482938339158989............................... you wouldn't want to measure out exactly that much.
So subtract 55 from 35
35 - 55 = -20
then, put -20 over 55
-20/55 equals -0.36 repeating, rounded to -0.36, which equals 36%
the negative stands for decrease, so it's around 36% decrease
