Answer:
<h3>
5.0</h3>
Step-by-step explanation:

The equation which the civil engineer can use to find the number of rows is 2x² - 12x = 112. Option D
<h3>How to determine the equation</h3>
Let the number of rows be x
Number of cars in each row = x - 6 = 56
Number of rows for parking lot = 2x
Then,
Number of cars for new parking lot = 2x ( x - 6 = 56)
Expand the expression,
2 ( x - 6 = 56)
2x² - 12x = 112
Thus, the equation which the civil engineer can use to find the number of rows is 2x² - 12x = 112. Option D

multiply the 2/3 x the 1/6 to get 1/9
so the original equation can be rewritten as 3^1/9
this can be rewritten as the 2nd choice 9cubed3
Answer:
undefined
Step-by-step explanation:
If you graph x=-1, you will get a line with x-intercept -1 and no y-intercept. If you do not have either of these things, your line does not have a constant slope.
