Step-by-step explanation:
One loan from the local bank is a three year loan with a capital of $75000 and an annual interest of 5%.
Therefore simple interest form this loan for the year will be
⇒ Principal amount×Rate of interest×Time(in years)/100
⇒ 75000×5×1/100
Interest = $3750
Other loan is a one year loan with a principal of $21000 and annual interest of 4.5%
Therefore interest of first year from this loan will be
= Principal amount×Rate of interest×Time(in years)/100
= 21000×5×4.5/100
= $4725
Total interest of first year for both loans = 3750+4725 = $8475
The formula to find any term of an an arithmetic sequence is given by
=
=(n-1)d,
where we have first term
=8,
and d which is the common difference , and n is the term we need to find (in our case is 20)
the difference d=3, as you see each number is the previous minus 3
for S20=8+(20-1)*(-3)=8+(19)*(-3)=8-57=-49
S20=-49, this the 20th term
To solve we have to write 12x as 2x+10x
<span><span>x2</span>+2x+10x+20</span>
taking x and 10 as a common
x(x+2)+10(x+2)
now (x+2) is common
<span>(x+2)(x+10) answer</span>
