If I'm doing this correctly, you would need to multiply everything inside the parenthesis by 8. So it would be 8x-24y·8x+24y. I'm sorry if that's not right, but that is my interpretation of the problem. Hope I was of some assistance :)

Let a = 8(x - 3y)(x + 3y)

by multiplying the functions in the bracket first
⇒   a  = 8[ x² + 3xy - 3xy - 9y²]
      a  = 8 [x² - 9y²]

by now expanding the brackets
⇒  a  = 8x² - 72y²

x+4x=15600

5x=15600

divide by 5 on both sides

Solve for x 11x+4<15 OR 12x−7>−25
never [62]

Isolate the x in both cases. What you do to one side, you do to the other.


11x + 4 < 15


Subtract 4 from both sides


11x + 4 (-4) < 15 (-4)


11x < 11


isolate the x, divide 11 from both sides


11x/11 < 11/11


x< 1


x < 1 is your answer for the first one

-------------------------------------------------------------------------------------------------------------------


Again, isolate the x.


12x - 7 > -25


Add 7 to both sides


12x - 7 (+7) > -25 (+7)


12x > -18


Isolate the x, divide 12 from both sides


12x/12 > -18/12


x > -1.5 is your answer for the second one.
