goldenfox [79]

Answer:

The answer to your question is below

Step-by-step explanation:

*A(x)=3x³ + 2x² - x           This polynomial is not divisible by (x - 1)

                                       Factor completely    3x(x + 1)(3x - 1)

*B(x)=5x³ - 4x² - x            This polynomial is divisible by (x - 1)

                                       factor completely   3x(x - 1)(5x + 1)

*C(x)=2x³ - 3x² + 2x - 1     This polynomial is divisible by (x - 1)

                                        Synthetic division      2   - 3  + 2  -1      1

                                                                                   2    -1    1                

                                                                            2    -1      1    0

*D(x)=x³ + 2x² + 3x + 2   This polynomial is not divisible by (x - 1)

                                        Synthetic division    1    2   3   2   1

                                                                                1    3   6                      

                                                                           1    3   6   8

You and your friend are painting the walls in your apartment. You estimate that there is 1000 square feet of space to be painted
leva [86]
After 45 minutes you will have painted 4*45=180 square feet.

so the total number of painted area, y, is:

y=180+x*(3+4) after the 45 minutes

where x is the number of minutes AFTER THE 45 minutes:

if y is 1000 then

1000=180+x*7
820=x*7
x=117.14

so 117 minutes, or one hour and 57 minutes.

Find two consecutive odd intefers whose product is 63
nikdorinn [45]
Two consecutive odd integers are known as back-to-back odd whole numbers; one right after the other.
For example; 1 and 3, 3 and 5, 5 and 7, and so on. Let’s work up to which two consecutive odd integers make a product of 63.
1 x 3 = 3; no
3 x 5 = 15; no
5 x 7 = 35; no
7 x 9 = 63; yes

From the work shown above, we can see that the two consecutive odd integers “7” and “9” make a product of 63.

I hope this helps!
