Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
Answer:
These outcomes are disjoint.
Step-by-step explanation:
(a) Are the outcomes none, small, and big disjoint
If they are disjoint, the sum of the total number of each has to be equals to the number of emails.
We have:
3921 emails.
549 with no numbers.
2827 with only one or more small numbers
545 had at least one big number.
549 + 2827 + 545 = 3921
Since the sum is equals to the number of emails, these outcomes are disjoint.
Answer:
11 y + 3
Step-by-step explanation:
(6y-2) + (5y+5)
Add 6y and 5y
11y - 2 + 5
Add -2 and 5
11 y + 3
$6.67 is 6.6666 rounded to the nearest cent.
What they said ^ I was just about to answer, but there’s popped up first lol
