Answer:
The length of the parking lot should be increased by 20 feet.
Step-by-step explanation:
First, you find the product of 120 and 80, you get 9600.
Next, add 4400 to it. You get 1400
Finally what would you add to both 120 and 80 to get 14000? 20 to get 140*100.
5.86 is your answer. This is because you would need to: 586/100=5.86
We want to factor 3a² - 5ab - 2b².
Note that
(3a)*(-2b) + a*b = -6ab + ab = -5ab
(3a)*a = 3a²
b*(-2b) = -2b²
Therefore
3a² - 5ab - 2b² = (3a + b)(a - 2b)
The factors are (3a + b) and (a - 2b).
Answer:
One of the factors is (3a + b).
Another factor is (a - 2b).
