Answer:
<em>(</em><em>2</em><em>x</em><em> </em><em>+</em><em> </em><em>1</em><em>)</em><em> </em><em> </em><em>(</em><em>3</em><em>x</em><em> </em><em>-</em><em> </em><em>4</em><em>)</em>
Step-by-step explanation:
Solution:
- 6x² - 5x - 4
- 6x²- (8 - 3)x - 4
- 6x²- 8x + 3x - 4
- 2x (3x - 4) +1 (3x - 4)
- (2x + 1) (3x - 4)
P= principal (initial deposit) ($7000)
i= interest (5%)
t= # of years (3)
Total amount = P (1 + i)^t
T= $7000(1 + 5%)^3
T= 7000(1.05)^3
multiply exponents before regular multiplication
T= 7000(1.157625)
Total= $8,103.38 after 3 years
Hope this helps! :)
