Answer:
For example, 8f + 4g is one of the most used expression
Another example is 4 (2f + g), is correct too
Circumference=2πr
=2*3.14*105
=659.4cm
Answer:
Step-by-step explanation:
To find the GCF we factor all the given terms and then find the Greatest Common Factor from both ,
So , The given two terms can be given by

Here common numbers that are in both are
2.7.c.c.d
so GCF= 
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
