Answer:
<h3>The answer is 243.</h3>
Step-by-step explanation:
To evaluate the expression substitute the values of a , b , c and d into the above expression
a = - 9
b = - 7
c = 9
d = 3
So we have
2cd + 3ab = 2(9)(3) + 3(-9)(-7)
= 2(27) + 3( 63)
= 54 + 189
We have the final answer as
<h3>243</h3>

Answer:
Inductive
Step-by-step explanation:
To Find the least common denominator you have to find the multiples of each number
multiple means the product of each factor
so the multiples of 4 would be 4 8 12 16 20
you want to name at least five multiples but if there are not the same multiples you might have to list more
the multiples of 5 would be 5 10 15 20
then I can stop there because I have found two of the same multiples
so now we have our least common denominator which is 20
HOPE THIS HELPS!!!
