Answer:
x = -10 or x = -3
Step-by-step explanation:
Here, the given equation is
The given equation can be solved by the method of SPLITTING THE MIDDLE TERM
Split 13 in such a way that sum of the terms = 13
and product of the terms = 30
So, the given equation becomes
Here, 10x+ 3x = 13x and 10 x 3 = 30
Now, simplifying the equation,
⇒ either (x+ 10) = 0 ,or (x+ 3) = 0
⇒ x = -10 or x = -3

Answer:
Semiannual payment = $ 1391.37
Total payment = $ 8348.22
Interest paid = $ 848.22
Step-by-step explanation:
Since, the semiannual payment formula of a loan,
Where,
PV = present value of the loan,
n = number of semiannual payments,
r = annual rate,
Here, PV = 7500, r = 6.3% =0.063, n = 6,
By substituting the value,
The semiannual payment would be,
Also, total payment = semiannual payment × total semiannual periods
= 1391.37 × 6
= $ 8348.22,
Also, the interest paid = total payment - present value
= 8348.22 - 7500
= $ 848.22
