Answer:

x = \frac{25}{7}

Step-by-step explanation:

Using the midline theorem

A segment joining the midpoints of 2 sides of a triangle ia

Parallel to the third side and half the length of the third side, thus

7x - 1 = 24 ( add 1 to both sides )

7x = 25 ( divide both sides by 7 )

x = \frac{25}{7}

Answer: Philip can earn back his initial investment in 12.4 years


Step-by-step explanation:


Amount Invested by Philips in period annuity = 800,000

Annual Percentage Rate (APR) = 5.2%

APR compounded monthly for a period of 20 years.


Amount to be received per annuity period = 800,000 * (((1+(0.052/12))^240)*(0.052/12))/(((1+0.052/12))^240)-1)

= 5368.43


Time taken ( in months ) by Philip to earn back his initial investment = 800,000/5368.43 = 149.02 months



Time taken ( in years ) by Philip to earn back his initial investment = 149.02/12 = 12.4 years


Hope it helps.

Thank you :)
