<u>Answer</u>

AC = 34

<u>Explanation</u>

It is given that,ΔACE,

B is the mid point of AC

D is the mid point of CE

and F is the mid point of AE

If D and F are the midpoints, The line joining D and F parallel to third side AC.

The two triangles ΔACE and ΔFDE are similar and their sides are in the ratio 1/2

Here FD = 17 therefore AC = 34

G(x)= 3/4x+6<br> What is the value of g(12)?

gizmo_the_mogwai [7]

Answer:

G(12) = 15

Step-by-step explanation:

When doing g(x) equations, all you do is substitute the value inside the parentheses to x in the equation.

So you get 3/4(12) + 6.

Then simplify to get g(12) = 15

<h3>What is compound interest?</h3>

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.

It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it, so that interest is generated the next period on the principal amount plus any accumulated interest. In finance and economics, compound interest is common.

It is given by formula

A = $p*e^{r*t}$
