Answer:
using the 7% interest rate the interest rate is 168 due to the fact if you take 2400 x .07 you get 168 however I don't know if it asks that but in order to see exactly how much money would be in there you would have to add the 168 to the 2400 if you are to add that to the 2400 that was originally put in the bank you would come up to 2568
This is a quadratic equation. There's a shortcut (two shortcuts really) called the Shakespeare Quadratic Formula (2b or -2b) applicable when the middle term is even:
OK, our problem is
Typically we'd write 
but the answers here don't so we won't either.
Answer: C and D
Since two of the triangles are similar that means they are the same thing :
<A = <L
108 = 108
<C is twice from <M so :
<C is 2x < M is x
as you note down the answer you can draw two triangles and label them according to thier values, you will see that triangle ABC has two things now ;
a = 108 and c = 2x
when you have two measures in a triangle you can find the 3rd one :
suppose that third < of triangle ABC is x ;
108 + 2x + x = 180
108 + 3x = 180
3x = 180 - 108
3x = 72
<u> </u>
<u> x = 24</u><u />
<u>
<m = 24 </u>
further if you want to find C : < c = 2x
< c = 2 ( 24 )
< c = 48
Answer:
sorry, the answer is undefined because negative in squer is undefined
