Answer: 8 units

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, so you can set AE and CE equal to each other, as well as BE and ED

2x=x+2

x=2

AC=2x+x+2

AC=3x+2

SUbstitute x

AC=3(2)+2

AC=6+2

AC=8

You invest $1,300 in an account with an annual interest rate of 2.5%, compounded monthly. How much money is in the account after
wariber [46]
Hi there
The formula is
A=p (1+r/k)^kt
A future value?
P present value 1300
R interest rate 0.025
K compounded monthly 12
T time 15 years
So
A=1,300×(1+0.025÷12)^(12×15)
A=1,890.75

Good luck!
