x=45

Answer 5

\[\sqrt{17x-60} =x\]

Answer 6

do u know how to solve quadratics ?

Answer 7

@hartnn i do :)

Answer 8

excellent!
so what did you get for your 2nd question ?

Answer 9

@hartnn no real solution the options for question 2 are
16

@hartnn but 3.7 i feel like could be the possible answer

Answer 12
