Answer:

(8x - 1)(7x - 1)

Step-by-step explanation:

Given

56x² - 8x - 7x + 1 ( factor the first/second and third/fourth terms )

= 8x(7x - 1) - 1(7x - 1) ← factor out (7x - 1) from each term

= (7x - 1)(8x - 1)

= (8x - 1)(7x - 1) ← in factored form

Answer:

The answer is 1st point.

Step-by-step explanation:

By following the steps that is shown in the picture :

56x² - 8x - 7x + 1

1.Group pairs of terms with common factor,

(56x² - 8x) + (-7x + 1)

2.Factor the GCF from each group,

8x(7x - 1) - 1(7x - 1)

3.Use distributive property,

(8x - 1)(7x - 1)

Answer:

$3100 is invested at 9%

$4900 is invested at 11%

Step-by-step explanation:

Let's take "x" be the amount invested at 9%.

(x + 1800) is invested in another account at 11%.

The interest amount earned by the two accounts is $818.

Here we can use the simple interest formula and find the amount invested in each account.

Simple interest (I) = , where P- is the principal , N is the number of years and R is the interest rate.

Simple interest =

0.09x + 0.11(x+1800) = 818

Now we have to simplify and find the value of x .

Use the distributive property and simplify the second term.

0.09x + 0.11x + 198 = 818

0.2x + 198 = 818  

0.2x =818 - 198

0.2x = 620

x = 620/0.2

x = 3100.

So $3100 is invested at 9%

x + 1800 = 3100 + 1800

= $4900

$4900 is invested at 11%

Hope this helped.

Divide: (-7x+x^2+15)÷(-3+x)
kakasveta [241]
Since the divisor is in the form (x + #) or (x - #), This can be done by synthetic division.
First put the polynomial ion descending order: x^2 - 7x + 15
Take the coefficients of the terms and follow these steps:

3 |  1 -7  15
         3  -12
___________  Bring down the 1, multiply the 3 by the 1 and place under the
     1  -4    3       -7, then add.
                         Multiply 3 by -4, place under the 15, then add.
       The bottom row is our answer. Since the problem started with a second power, the answer will start with a first power.
The bottom row are the coefficients of the terms and the last number is the remainder.
x - 4 remainder 3 ALSO WRITTEN   x - 4 + 3/(x -3)
