The first one because if you simplify 4(m+12) you get 4m+12!! :)
The sum of two variables having the same units is given by adding the magnitudes of the quantities and expressing the outcome in the units of the quantities
Daemon's speed is (v + 45) mi/h
The reason the above value for Daemon's speed is correct is as follows:
The known parameters are;
The speed with which Bill was travelling = v mi/h
The speed with which Daemon was travelling = 45 mi/h faster than Bill
Method:
By dimensional analysis, we note that the given quantities have the same units, and therefore, they represent the same quantity of speed
To find Daemon's speed, the amount by which his speed is more than that of Bill's speed is added to the given amount of Bill's speed as follows;
Solution:
Daemon's speed = v mi/h + 45 mi/h = (v + 45) mi/h

Answer:
Step-by-step explanation:
Given
See attachment
To answer this question, we start by equating the denominators of each option to 0; then, solve for x
(a):
This gives
Set the denominator to 0
Solve for x
Factorize:
This implies that:
From above, one of the values of x is 7.
This implies that x = 7 is an excluded value for this quotient.

The particular identity you want to use is
Then
Expand the binomial to get
Use the identity again to write
and so
