Umm isn’t it 36 I don’t know
Answer:
Below in bold.
Step-by-step explanation:
No repetition.
There are a total of 7 numbers.
For the number to be even it must end in 0, 2 or 8.
The other 3 numbers will be the number of permutations of 3 from the 6 other numbers.
Number of 4 digit numbers ending in 0
= 6P3 = 6! / 6-3!
= 120.
Now the number could also end in 2 or 8,
so there are 3*120 = 360 4-digit even numbers (no repetition).
With repetition.
There are 3 * 7^3 = 1029 with repetition.
Answer:
16w+40
Step-by-step explanation:
To simplify this equation you have to use the distributive property first. This means you multiply 4 by everything in the first set of parentheses and you multiply 6 by everything in the second set of parentheses. This leaves you with 4w+16+24+12w.
Next, you combine like terms by adding 4w and 12w to get 16w, and 16 and 24 to get 40.
So, your final answer is 16w+40.
(3x-4)+(5x-26)
3x-4+5x-26
8x-30 = FG
