Answer:
133 windows
Step-by-step explanation:
38/2=19 (windows per 1 hour)
19*7=133 windows
The answer is 7.7 that is the answer
This is about understanding GCMF.
<em><u>GCMF = x</u></em>
- GCMF is simply an abbreviation for greatest common factor.
- It is the highest factor that is common to 2 or more numbers or figures.
- We want to find the GCMF of x² + 2x.
- Let's list the factors of both;
Factors of x² = x, x
Factors of 2x = 2, x
- The factor common to both of them is x.
Thus,
GCMF = x
