How much interest is earned on $2,700 in one year if it is invested at 3%?

Interest would be $81.00.

Step-by-step explanation:

To find out the interest earned on $2,700 in one year if it is invested at 3%.

We use the formula to get interest :

I = Prt

Where P = principal amount ( $2,700 )

r = rate of interest 3% in decimal  ( 0.03)

t = time (1 year)

Now put the values in formula

I = 2,700 × 0.03 × 1

I = $81.00

The earned interest is $81.00 on 2,700 in one year.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
