Answer:
$1,250
Step-by-step explanation:
You can find the answer using the following formula:
i = Prn
i= interest= $400
P= principal
r= rate of interest=0.04
t= time periods= 8
You can replace the values you have in the formula and then, isolate P:
400= P*0.04*8
400=P*0.32
P= 400/0.32
P= 1250
According to this, the answer is that Anna borrowed $1,250.
Answer:
4th option
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 
- (3x² - 3x - 5)
= 4x² - 3x² + 3x + 5 ← collect like terms
= x² + 3x + 5
