Answer:
Step-by-step explanation:
you just give 2 a common factor
2(-5x+1)
For this case we have by definition, the GFC of two numbers is given by the largest factor that divides both numbers without leaving residue.
We have the following expression:
and 
So, we look for the factors of 3 and 4:
3: 1.3
4: 1, 2, 4
Thus, the GFC of both numbers is "1".
The GFC of both expressions is: 
Answer:
p
Answer:

multiply x through out:

factorise out x²:

take square root on both sides:

The angles look like

F- angles are corresponding angles.
Corresponding angles are congruent.
Answer:
Step-by-step explanation:
you put the -9 above where it says the -9 and same to the -3
or to solve the equation:
Divide both sides of the equation by the same term
−9=−3−9−3=−3−3
Divide the numbers
−9−3=−3−3
3=−3−3
Cancel terms that are in both the numerator and denominator
Move the variable to the left =3x=3
Solution =3
