Answer:
9x+4
Step-by-step explanation:
Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4
Answer:
B.(x-6)
Step-by-step explanation:
12/(x^2 - 11x+30) - 43/(x^2-6x)
12/((x - 5) (x - 6)) - 43/x(x-6) [Factoring the denominator]
Both have x-6 common in the denominator,
It would be 23.5 idk if your aloud to do that
or 141/6
