Given

( 3x - 2 ) ( x² + 5x - 8 )

= 3x ( x² + 5x - 8) - 2 ( x² + 5x - 8)

= 3x³ + 15x² - 24x - 2x² - 10x + 16

= 3x³ + 13x² - 34x + 16

Aleks04 [339]

Answer:

13.4%

Step-by-step explanation:

First year:

$10,000*6% = $600

New balance = $10,600

Second Year:

$10,600*7% = $742

$10,600+ $742 = $11,342

Total Return:

Final Balance - Initial balance

$11,342 - $10,000 = $1,342

$10,000*x ÷ $1,342

x = $1,342/$10,000

x = 0.1342

0.134 = 13.4%

A 0

B.5/2

c. 23

D. 5

<h3><u>Answer:</u></h3>

Option D

The solution to given equation is x = 5

<h3><u>Solution:</u></h3>

Given that we have to solve the given equation

4(6x - 10) = 8x + 40

Let us solve the above expression and find value of "x"

Multiplying 4 with terms inside bracket in L.H.S we get,

24x - 40 = 8x + 40

Move the variables to one side and constant terms to other side

24x - 8x = 40 + 40

Combine the like terms,

16x = 80

$x = \frac{80}{16} = 5$

Thus solution to given equation is x = 5
