The length of a rectangle is represented by 2a + 4b, and its width is represented by 3a − 2b. Enter the polynomial for the perimeter of the rectangle. What is the minimum perimeter of the rectangle if a = 12 and b is a non-zero whole number?

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
