Answer:
30 Pencils
Step-by-step explanation:
If Patrick has 2 pencils, and Phyllis has 7 more than him, phyllis has 9 pencils.
But Phyllis has 12 less pencils than Nadine, we can find how many pencils Nadine has by adding 7+12=19
Nadine has 19 pencils
Now we add these all together
2+9+19= 30
All together, they have 30 pencils.
Hope this helps! Have a great rest of your day! :)
Answer:
True for all values of a, b and c.
Step-by-step explanation:
(a–3c)(4c+2a)+3c(a+3c)=(2a–c)(3c+5a)–8a^2
Left side:
(a–3c)(4c+2a)+3c(a+3c)
= 4ac + 2a^2 - 12c^2 - 6ac + 3ac + 9c^2
= 2a^2 + ac - 3c^2
Right side:
(2a–c)(3c+5a)–8a^2
= 6ac + 10a^2 - 3c^2 - 5ac - 8a^2
= 2a^2 + ac - 3c^2.
So we see that the left side is identical to the right side so it is true for all values of the variables.
I would say 2.5 becasue there are two lines between the -2 and -1 so it would be half. SO my awnser is 2.5
i hope this helped you
Have a good day

Answer:
1246 teams
Step-by-step explanation:
We are told there are 7women & 6men.
If 5 people are selected and there must be more women than men in the team.
This means there must be a minimum of 3 women.
Thus;
For 3 women;
7C3 × 6C2 = 525
For 4 women;
7C4 × 6C3 = 700
For 5 women;
7C5 × 6C0 = 21
Thus;
Total = 525 + 700 + 21 = 1246 teams
