Answer:
y=6+2x
Step-by-step explanation:
If you divide both sides by -4 you get

So, you wrote the equation in the form y=kx, and in this form k is the constant of variation. So, the constant is -2.
Answer:
Approach: Difference of Squares Pattern

Step-by-step explanation:
The given binomial is:

We can rewrite to obtain:

This is a difference of two squares, so we will factor using difference of squares pattern.
Recall that:

If we let

and

Then we can factor the given binomial to obtain:


Answer:
z+42+42=180
Step-by-step explanation:
Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to 180. So use this equation:
z+42+42=180
If you need to find z, it is 96.
Check: 96+42+42=180
