Which method? There is the substitution method, elimination method, and comparison method
Answer:
-14
Step-by-step explanation:
a-4c=(-6)-4(2)=-6-8=-14. Hope this helps!
One way to solve this is to use Pythagorean theorem: the square of one leg of triangle plus square of other leg of the triangle equals c the hypotenuse (longest side of triangle). You might see this as the formula a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse.
In this case, the legs are 3√2 and the hypotenuse is h.
Using the formula:
(3√2)² + (3√2)² = h²
18 + 18 = h²
h = 6
The other way to do this is with trigonometric angles.
Remember cosine is adjacent over hypotenuse.
cos(45°) = (3√2) / h
h = (3√2) / cos(45°)
h = 6
80,000 per year....there are 12 months in a year
80,000 / 12 = 6666.67 per month
