The greatest common factor (GCF) of 9, 21 and 60 is: 3
Factors of 9: 1, 3, 9
Factors of 21: 1, 3, 7
Factors of 60: 1, 2, 3, 4, 5, 6
The common factors between the three numbers are 1 and 3, but since 3 is the highest number, it is considered the GCF.
Answer:
Mia is incorrect.
Step-by-step explanation:
She confused the area and perimeter.
Area is length x width, in this case 12 x 5 = 60
Perimeter is length² × width², and in this case, it is 12² × 5² = 34
Area = 60 inches
Perimeter = 34 inches
Hope that helps and have a great day!
Answer:
- 48
Step-by-step explanation:
If you want to learn more about this concept, it's called composition of functions.
First, you plug in g(x) as if it were x into f(x).
f(g(x))= -5 (1/2x + 4) + 2
= -5/2x - 20 + 2
= -5/2x - 18
Then, plug in the value given, as x.
= -5/2 (12) - 18
= -30 - 18
= - 48
I hope this helped!
