This is obvious, 2/10 is less than one
10/6 is more than 1 so
2/10<1<10/6
therfor 2/10 is less
the legit way to do it is
convert bottom numbers to same number
number is 30
2/10 times 3/3=6/10
10/6 times 5/5=50/30
6/10<50/30
Answer: A.
Step-by-step explanation: yes
The formula of the present value of an annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 280000
PMT monthly payment?
R interest rate 0.06
K compounded monthly 12
N time 20 years
Solve the formula for PMT
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
PMT=280,000÷((1−(1+0.06÷12)^(
−12×20))÷(0.06÷12))
=2,006.01
x%*120=36
x/100 *120=36
120x/100=36
120x=3600 <em>/:120</em>
<em>x=30</em>
<em>⇒36 is 30% of 120 </em>

There are two expressions which do not match with the written descriptions to ist right.
Those are:
1) (4x - 3)^2 - 1: see that the written description does not square the difference of 4x and 3
2) 3(5x^2 + 14x + 7): see that the written description tells that 5 is added to the square ox x, which is not what the expression shows.
The other 4 expressions match with the written descriptions.
So, you can choose those other 4 expressions.
