Answer:

ok so I got two different answers

5xtimes3x+28

5times3=15x

15x=28

28/15=1.866666667

x=1.867

or

5x+3x+28

5+3=8x

8x=28

8/28=3.5

x=3.5

Answer:

0 or -9.33

Step-by-step explanation:

We can find x by making the equation equal to 0:

[tex]5\cdot{x}\cdot{(3\cdot{x}+28)}=0[/tex]

Therefore x can equal:

[tex]5\cdot{x}=0[/tex]

[tex]x=0[/tex]

or

[tex]3\cdot{x}+28=0[/tex]

[tex]x=-28/3=-9.33[/tex]
