Answer:
the lcm of 15 and 18 is 90 and the gcf is 3
Step-by-step explanation:
multiple factors to get lcm and to get GCF Find the prime factorization of 15
15 = 3 × 5
Find the prime factorization of 18
18 = 2 × 3 × 3
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 3
Let me do it but give me time is the answer to this question
I wanna say 9.6 inches
Because 4 divided by 50 is 0.08 and 120 x 0.08 is 9.6
C(n) = 20n + 15
<span>y = 20n + 15 </span>
<span>20n = y - 15</span>
<span>n = (y - 15)/20 </span>
B.)
<span>N(c) = (c-15)/20
