Answer:
B
Step-by-step explanation:
B
x - 4 squared provides 2 real zeros that are the same. These two are not distinct.
The other two come from x^2 - 7x + 10 which has a discriminate of
sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.
Answer: 30
Reason: you divide 60=2x which makes x=30
Each roll contains 80cm which is the same as 0.8 meters. Because he needs 5.6 meters, divide 5.6 by 0.8 and you 7. The seven is the number of rolls of tape he will need to purchase. Each roll costs $5 so multiply 7 by 5 and you will see that Carson will need to spend $35 if he wants to get that much tape. Hope that helps!
