Answer:
D. 
Step-by-step explanation:
Hello!
We can group the first two terms and the last two terms.
<h3>Factor by Grouping</h3>
Factoring by grouping is the process of breaking down larger polynomials to smaller ones to factor. We can then combine like factors.
In the second step, we can see that we can rewrite
as
, as both the two terms share a common factor of
. We can pull out
from that expression. Similarly,
and
share a common factor of
, so we can pull that out.
Answer:
n = 2
Step-by-step explanation:
1.2n - 1.5 = 0.45n
collect like terms
1.2n - 0.45n = 1.5
0.75n = 1.5
divide both side by 0.75
0.75n/0.75 = 1.5/0.75
n =2

Answer:
Step-by-step explanation:
<u><em>The question with some background info added:</em></u>
- <em>When measuring the dimensions of a room a carpenter uses a tape measure that only displays a number of feet, L, on the metal tape. (The carpenter's tape measure does not display inches) </em>
- <em>Write an expression to determine the length of the room in units of 3 feet. </em>
<h3>Solution</h3>
Let the length of the room be L feet measured by the carpenter
<u>Then</u>
- L/3 = 1/3L would be measure of the length in units of 3 feet
