Given the figure below, find EF if CA = (6n) and EF = (n + 8)

GalinKa [24]

Answer:

$EF = 12$

Step-by-step explanation:

Given

$CA =6n$

$EF= n + 8$

Required

Find CN

From the attachment:

$EF = CD\ and\ CD = DA$

Where

$CA = CD + DA$

This means that:

$CA = CD + CD$

$CA = 2CD$

$CA = 2*EF$

This gives:

$6n = 2*(n+8)$

Open bracket

$6n = 2n+16$

Collect anf simplify like terms

$4n = 16$

$n= 4$

So:

$EF= n + 8$

$EF = 4 + 8$

$EF = 12$

Martha is buying a house for $107,820. She is making 15 percent down payment and financing the remainder at 6.5 percent for 25 y

stellarik [79]

Given:
Total price : 107,820
down payment 15% of the total price.
financing the remainder at 6.5% for 25 years.

How much is she financing? She will finance 85% of the total price.

107,820 * 15% = 16,173
107,820 - 16,173 = 91,647

or
107,820 * (100-15)% = 107,820 * 85% = 91,647
