What two factors of 48 add up to -16? -4 and -12

So the factored form would be (x-4)(x-12)

Answer:

(x-12)(x-4)

Step-by-step explanation:

x^2 - 16x + 48

In the given expression , the product is 48 and sum is -16

-4 times -12 gives us 48

-4 plus -12 gives us -16. So two factors are -4 and -12

Beak the middle term using factors

x^2 -4x-12x+48

Group first two terms and last two terms

(x^2 -4x)+(-12x+48)

FActor out GCF from each group

x(x -4)-12(x-4)

FActor out x-4 that is in common

(x-12)(x-4)

Mark incorrectly solved the inequality -4(5/2+3/2x) > 8. His work is shown. Which step shows an error based on the inequality
aliya0001 [1]

Answer : The incorrect step is, (A) step 1: -10 + 6x > 8

Step-by-step explanation :

The given expression is:

-4(\frac{5}{2}+\frac{3}{2}x)>8

Now solving this expression step by step.

First -4 distributed over parentheses.

(-4\times \frac{5}{2})+(-4\times \frac{3}{2}x)>8

Now solving bracket term, we get:

-10-6x>8

Now taking like terms together, we get:

-6x>8+10

-6x>18

-x>3

Now multiplying this expression by (-1), we get:

x>-3

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8

Anna has 1/2 hour of free time. She divides the time equally between walking her dog and playing her favorite song on the piano.
vichka [17]

Answer:

The answer to your question is:

Step-by-step explanation:

Data

1/2 hour free time

divide equally playing her favorite song and walking her dog

              Free time = F

              = 1/2 hour or 30 min

She divided equally her free time between walking her dog and palying her favorite song.

            30 min / 2 = 15 min

She has 15 min to walk her dog and 15 min to play her favorite song.

If she played her song 3 times, then:

              15 min / 3  = 5 min

Her favorite song lasts 5 min.
