The number 20<span> is a composite number so, it is possible to factorize it. In other words, 20 can be divided by 1, by itself and at least by 2 and 5. A composite number is a positive integer that has at least one positive divisor other than one or the number itself. In other words, a composite number is any integer greater than one that is not a prime number.</span>
<span>The prime factorization of </span>20<span> = 2</span>2•5.
<span>The prime factors of </span>20<span> are 2 and 5.</span>

Answer:
m∠CBD=68°
Step-by-step explanation:
BA is perpendicular to BD, meaning they form a right angle (90°)
This means m∠CBD + m∠ABC=90, or they are supplementary.
We have expressions given for these angles, so
4x+52+8x-10=90
12x+42=90
12x=48
x=4
Knowing x=4, we can substitute back into our expression for m∠CBD because that's what we're looking for.
4(4)+52=68
m∠CBD is 68°.
Jacob had math homework on 81 evenings.
Step-by-step explanation:
Time spent of each evening = 1/3 of an hour
Time spent in minutes = 
Total time spent = 27 hours
Total time spent in minutes = 27*60 = 1620 minutes
Let,
x be the number of evenings spent doing math homework.
Time spent each day* Number of evenings = Total time spent
Dividing both sides by 20
Jacob had math homework on 81 evenings.
