Answer:
-2
Step-by-step explanation:
divide -3 from both sides
Answer:
The greatest common factor of the terms is 1.
Step-by-step explanation:
The terms have no variables in common, and the coefficients have no factors in common. The greatest common factor of the terms is 1.
__
The discriminant is negative (40² -4(30)(51) = -4520), so any linear factors will be complex.
For this case we have the following expression:

We must rewrite both sides of the equation.
For this, we use the distributive property.
We have then:

Adding similar terms we have:

We observe that we have two equal equations.
Therefore, the equations intersect for any value of x.
Thus, the equation has infinite solutions.
Answer:
infinitely many
You know this is just a formula, right?
Answer:
60
Step-by-step explanation:
Use C rule (also known as allied angle)
Therefore angle 3 and 6 add up to 180 degrees.
So basically subtract 120 from 180 which gives you 60 degrees
