Answer:
The expression that uses the distributive property to represent the sum of 39 + 27 is
Step-by-step explanation:
Given
Expression: 39 + 27
Required
Express using the distributive property
The distributive property is represented in the form a(b + c)
So, we can say that the meaning to the question is that the given expression should be represented in the form a(b+c)
Equate these two expressions, we have
Factorize the expression on the left hand side
Simplify fraction
Compare expression on left hand side with the expression on the right hand side.
Since, they have the same format, then we've arrived at the answer.
Hence, the expression that uses the distributive property to represent the sum of 39 + 27 is
Answer:
resistance is 1.5 ohms (1.5 Ω)
Step-by-step explanation:
R varies directly with l
R varies inversely with
We can set-up a proportionality statement as shown below:
Now, Given,
R = 1.50
l = 2
d = 1.5
We substitute and find k (the proportionality constant):
Now, we will use this value of k to solve the problem.
Given,
l = 8
d = 3
and
k = 1.6875
We find R:
The resistance is 1.5 ohms (1.5 Ω)
