Answer:
x = 7, x = -2
Step-by-step explanation:
(x-7) (x+2) = 0
Zero product property: In order to get a product (the answer to a multiplication problem) of 0, you need to have at least one of the numbers being multiplied be 0. For example, in x * y = 0, either x or y needs to be equal to 0.
Using this, we know that either (x - 7) or (x + 2) is 0. So,
x - 7 = 0
Add 7 to both sides.
x = 7
x + 2 = 0
Subtract 2 from both sides.
x = - 2
So, the answer is x = 7 or x = -2
20% Because $18.00 - $14.40 = $3.60
3.6/18 = 0.2 ---> 20%
The intercept are the number of each of the pots used when no soil was put in the other pot.
When no soil was put in the large pots, then 120/5 = 24 small pots will be filled.
When no soil was put in the small pots, then 120/12 = 10 large pots will be filled.
THerefore, the points labelled are (24, 0) and (0, 10)
