Answer:
$2000
Step-by-step explanation:
The amount of interest you pay (for simple interest) is the product of the original amount, the interest rate and the time in years. Let x be the original amount (how much money she borrowed):
720=x(0.09)(4)
720=0.36x
x=2000

Cluster Sampling
Step-by-step explanation:
I cant be 100% sure as i am not in statistics, but by definition cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research (in this case its the phone book).

so that appears to be what is happening in this scenario.
If it’s congruent it should be 1:1
Answer:
Step-by-step explanation:
(7x^2-5x+3)
+(2x^2+4x-6)=9x^2-x-3
A is c and a because it's on the left of 0.
B is b and d because it's on the right of 0.
