Answer:

Step-by-step explanation:

i'm either really confused or there's a lot of weird typos in this

assuming there's just a lot of weird typos, this is how you would solve it:

1. plug in -1 for a and 3 for b

$3(-1)(3)+50-6$

2. multiply 3 by -1

$3(-3)+50-6$

3. multiply 3 by -3

$-9+50-6$

4. add 50 to -9

$41-6$

5. subtract 6 from 41

$35$

304/320 simplified, please help, the faster the better.

Reika [66]

$\frac{304}{320} \\ \\ GCF = 16 \\ \\ 304 \div 16 = 19 \\ \\ 320 \div 16 = 20 \\ \\ \frac{19}{20} \\ \\$

The final result is: 19/20 or 0.95.
