Answer:
10.
Step-by-step explanation:
x^2 + 5x = 150
x^2 + 5x - 150 = 0
This equation will factor:
(x - 10)(x + 15) = 0
x - 10 = 0 or x + 15 = 0, so:
x = 10 or -15.
 
        
                    
             
        
        
        
Answer:
B. 
Step-by-step explanation:

Answer: Florida has 2.8865 million acres of cropland .
Explanation:
Since we have given that
Length of acres of cropland Alabama has = 2.51 millions
According to question, we have Florida has about 1.15 times as much cropland as Alabama has ,
