Answer:
B
Step-by-step explanation:
The formula for the area of a triangle is given as:
A = ½*base*height
A = ½*b*h
A = (bh)2
If we know the area (A) and the base, to find the height, the following would be done:
Divide both sides by b
A/b = h/2
Multiply both sides by 2

As we can see here, to find the base, we would divide the area by the vase, then multiply what we get by 2.
The highest common factor of 12 and 30 is 6;
6 divides both numbers without leaving a fraction
Add 6 to both sides
Solution: k = -30
