$650-100=$550
30x=550 where x is number of weeks
divide each side by 30
x=18.33 weeks so 19 weeks
Hope that helps.
If you square a number then get the square root of that, you end up with the original number.
Answer:
My step-by-step explanation:
1. First thing we do is: Distribute
(x+8)(x−5)x
(x−5)+8(x−5)
2. Second thing:Distribute
x(x−5)+8(x−5)
x^2−5x+8(x−5)
3.Third thing: Distribute
x^2−5x+8(x−5)
x^2−5x+8x−40
4. Fourth thing: Combine like terms
x^2−5x+8x−40
x^2+3x−40
5.And finnaly we find: The solution
x^2+3x−40
Good Luck!
