3x/3 =18/3
x = 6
Answer:
21
Step-by-step explanation:
Factors of 35 = 1,5,7 and 35
Factors of 15 = 1,3,5 and 15
=> Largest prime number that is a factor of 35 = 7 (7 is a prime number)
=> Smallest prime number that is a factor of 15 = 3 ( 1 is neither a prime no. nor a composite one)
<u><em>Their Product:</em></u>
=> 7×3
=> 21
Y=0x + -5 should be the correct answer
