Answer:
$9,399.20
Step-by-step explanation:
multiply the original amount by the percentage
6,200*4.3=26,660
Then divide 26,660 by 100
26,660/100= 266.6
Multiply 266.6 by 12
266.6*12=3199.2
<u>So, $3,199.20 were added to your account over 12 years </u>
Add $3,199.20 and $6,200
$3,199.20+$6,200=$9,399.20
So, after 12 years you would have $9,399.20 in your account
Answer: Choice A, x=-4
Step-by-step explanation:
1. 9x−(3x+9)=2x−25
2. 9x-3x-9=2x-25
3. 6x-9=2x-25
4. 6x-9=2x-25
-2x -2x
5. 4x-9=-25
+9 +9
6. 4x=-16 (divide both sides by 4)
7. x=-4
Answer:
25x^2 -1
Step-by-step explanation:
If you multiply parentheses:
(5x*5x) + (5x*-1) + (1*5x) + (1*-1)
25x^2 - 5x + 5x -1
25x^2 -1
A simpler way is to memorize this formula
(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)
