Numbers whose only factors are 1 and itself is known as prime numbers , numbers whose factors besides 1 and itself are composite numbers, we can use the sieve of Eratosthenes to determine whether the number is prime or composite.
Given a paragraph in which there are blanks:
A _____ is a number whose only factors are 1 and itself. If a number has factors besides 1 and itself, it is called a _____. You can use divisibility rules or _______ to help you determine whether a number is prime or composite.
We are required to fill the blank with appropriate options.
We have to fill "prime numbers" in the first blank.
We have to fill "composite numbers" in the second blank.
We have to fill "the sieve of Eratosthenes" in the third blank.
Hence numbers whose only factors are 1 and itself is known as prime numbers , numbers whose factors besides 1 and itself are composite numbers, we can use the sieve of Eratosthenes to determine whether the number is prime or composite.

Answer:
Y = 90
X = 52
Step-by-step explanation:
Y is on a straight line. The sum of the angles on a straight line is 180.
The only other angle (that is marked) on this straight line, is a 90 degree one. So, <y + 90 = 180.
<y = 90.
Now <x + 38 = 90
so, x = 52
Answer: C. 10
Explanation:
Take half right triangle from the isosceles triangle:
We get side lengths:
12/2 = 6, 8, and x
And use Pythagorean’s theorem to find x:
6^2 + 8^2 = x^2
36 + 64 = x^2
100 = x^2
10 = x
