Answer:
B. (-7 +/-√33) / 4
Step-by-step explanation:
2x2 + 7x + 2 = 0
x = [-7 +/- √(7^2 - 4*2*2)] / 2*2
x = -7/4 +/- √(33) / 4
= (-7 +/-√33) / 4
Answer:
A
Step-by-step explanation:
Answer:the expression is 5x - 2
Step-by-step explanation:
The number of customers in a store on the first day is represented by: (6x - 3).
The number of customers on the second day is represented by: (x - 1)
An expression to find how many more customers visited the store on the first day would be the difference between the number of customers that visited the store on the first day and the number of customers that visited the store on the second day. The expression becomes
6x - 3 - (x - 1)
= 6x - 3 - x + 1
= 6x - x - 3 + 1
= 5x - 2
Answer:
B
Step-by-step explanation:
