Answer: $4512 was the amount she borrowed.
Step-by-step explanation:
SI = 1692
R = 15% = 0.15
T = 30 months = 2.5 years
SI = PRT
1692 = P x 0.15 x 2.5
1692 = 0.375P
P = 1692 / 0.375
P = 4512
n: d = 27 because 27 minus 4 equals 23
Answer:40
Step-by-step explanation:
Answer:
0+7i
Step-by-step explanation:
The real part of the expression ('a') is zero. We have shown that, so it will be in the required form. Ordinarily, 0 would not be shown when writing this number.

We have taken the question to mean the principal square root. -7i is also a root of -49.
Plug in x = -4 and then use PEMDAS to simplify
f(x) = 5(3-x)^2
f(x) = 5*(3-x)^2
f(-4) = 5*(3-(-4))^2 ... replace every x with -4
f(-4) = 5*(3+4)^2
f(-4) = 5*(7)^2
f(-4) = 5*(49)
f(-4) = 245

Final Answer: 245
