Only if the they're both the same number. Then, their common value IS
also their greatest common factor AND their least common multiple.
600 + 300+ 150 + 75
divide by 2
Solution:
we have been asked to find
The smallest value of n such that the LCM of n and 15 is 45.
The prime factors of 15 are
So in LCM of n and 15 , we must include both the prime factors and the LCM is 45.
Since 3 is one time in the prime factor of 15. But to make 45 we need one more 3 and its possible if we take the value of n as below"
n=9
Hence the LCM will be
Hence the smallest possible value of n is 9.
Let the smaller number be x.
Larger number = 12 + x
Sum = 84
x + 12 + x = 84
2x + 12 = 84
2x = 72
x = 36
Hence, the numbers are 36 and 48.
F o g is how it's written with the -3 it means
f(g(-3))=what
so first -3 into g(x)
g(-3)=-4(-3)
g(-3)=12
sub for x in f(x)
f(12)=-3(12)^2-5
f(12)=-3(144)-5
f(12)=-432-5
f(12)=-437
