The factorization of a trinomial is modeled with algebra tiles. Which trinomial is factored? x2 + 3x – 6 x2 + 5x – 6 x2 + 3x – 2

Alisiya [41]

Answer

The answer is x^2 + 5x - 6

Step by step explanation

You are given four trinomials, we have to find which trinomial is factorable.

x^2 + 3x - 6 cannot be factored.

x^2 + 5x -6 can be factored.

= (x + 6)(x -1)

The factors are (x-1) and (x - 6)

Other twos are cannot be factored.

The answer is x^2 + 5x - 6

Thank you.

Select all the equations that are true. 24 x − 8 = 8 ( 3 x − 1 ) 24 x − 8 = 8 ( 3 x − 1 ) 6 m − 15 = 3 ( 2 m − 5 ) 6 m − 15 = 3

galina1969 [7]

Answer:

$24x - 8 = 8 ( 3 x - 1 )$

$6 m - 15 = 3 ( 2 m - 5 )$

$-7 x - 1 = - 1 ( 7 x + 1 )$

$-8 x -12 y - 16 = - 4 ( 2 x + 3 y + 4 )$

Step-by-step explanation:

Required

Select which of the equation is true

$24x - 8 = 8 ( 3 x - 1 )$

Open the bracket on the right hand side

$24x - 8 = 8 * 3 x - 8 *1$

$24x - 8 = 24x - 8$

Both sides of the equation are equal.

Hence, this equation is true

$6 m - 15 = 3 ( 2 m - 5 )$

Open the bracket on the right hand side

$6m - 15 = 3 * 2m - 3 * 5$

$6m - 15 = 6m - 15$

Both sides of the equation are equal.

Hence, this equation is true

$-7 x - 1 = - 1 ( 7 x + 1 )$

Open the bracket on the right hand side

$-7x - 1 = -1 * 7x -1 * 1$

$-7x - 1 = -7x -1$

Both sides of the equation are equal.

Hence, this equation is true

$16 a + 24 b = 8 ( 8 a + 16 b )$

Open the bracket on the right hand side

$16a + 24b = 8 * 8a + 8 * 16b$

$16a + 24b = 64a + 128b$

Both sides of the equation are not equal.

Hence, this equation is false

$-8 x -12 y - 16 = - 4 ( 2 x + 3 y + 4 )$

Open the bracket on the right hand side

$-8 x -12 y - 16 = - 4* 2 x -4 * 3 y -4 * 4$

$-8 x -12 y - 16 = -8x -12y -16$

Both sides of the equation are equal.

Hence, this equation is true

Alondra received a 14% hourly raise, but the number of hours worked decreased by 7.5%. If her wage was $10.50 an hour and she wo

Elodia [21]

Answer:

She will earn $442.89 in one week after the changes.

And this is more than her previous weekly earnings.

Step-by-step explanation:

Given:

Alondra received a 14% hourly raise, but the number of hours worked decreased by 7.5%. If her wage was $10.50 an hour and she worked 40 hours per week before the changes.

Now, to find money she will earn in one week after the changes.

Her wage was = $10.50.

She worked per week = 40 hours.

So, her salary before changes:

$10.50\times 40\\\\=\$420.$

Thus, the salary per week before changes is $420.

Now, to get her salary after 14% hourly raise:

$10.50+14\%\ of\ 10.50\\\\=10.50+\frac{14}{100} \times 10.50\\\\=10.50+1.47\\\\=11.97$

Salary after hourly raise = $11.97 per hour.

Then, to get the number of hours worked decreased by 7.5%:

$40-7.5\%\ of\ 40\\\\=40-\frac{7.5}{100} \times 40\\\\=40-3\\\\=37.$

Number of hours per week after hours of worked decreased = 37 hours.

Now, to get the salary after changes:

Salary after hourly raise × number of hours per week after hours of worked decreased

$=11.97\times 37$

$=\$442.89.$

Salary after changes in one week = $442.89.

As, the previous salary was $420 in one week. 

And after changes this salary is $442.89 in one week which is more than previous. 

Therefore, she will earn $442.89 in one week after the changes.

And this is more than her previous weekly earnings.
