Answer:
no solutions
Step-by-step explanation:
3(-n+4)+5n=2n
Distribute
-3n +12 +5n = 2n
2n+12 = 2n
Subtract 2n from each side
12 = 0
This is never true so there are no solutions
Answer:
- 12x² + 9x + 9
Step-by-step explanation:
(- 10x² + 2) + (- 2x² + 9x + 7 ) ← remove parenthesis
= - 10x² + 2 - 2x² + 9x + 7 ← collect like terms
= - 12x² + 9x + 9
20 now give brainly
if that is not it its -20
Because there were 15 yellow balls and 60 in total:
15/60
We can simplify:
1/4
Multiply both sides by 25:
25/100
The relative frequency is 25%
multiply everything together
there are 26 letters and 10 digits
so 26 x 26 x 10 x 10 x 10 = 676,000 combinations
