Answer:
Step-by-step explanation:
(x+1)(x−3)(x−4)
=((x+1)(x−3))(x+−4)
=((x+1)(x−3))(x)+((x+1)(x−3))(−4)
=x3−2x2−3x−4x2+8x+12
=x3−6x2+5x+12
You would use distribution. So, in this case, it would be 10a - 50. You use -10 to multiply -a and 5, and you get 10a, and -50.
Answer:

Step-by-step explanation:
There are 6 values on a die, and we want 2 values. The fraction now is
. But, wait! We can simplify this fraction:
.
Side note:
I understand if you wanted just the
fraction and not simplified.
3(2a+1)=-5(a+6)
First expand the brackets.
6a+3=-5a-30
Now add 5a to both sides.
11a+3=-30
Then subtract 3 from both sides.
11a=-33
Finally divide both sides by 11.
a=- 33/11
=-3
Answer:
Step-by-step explanation:
In order to find who is more efficient at planting carrots, we want to put both ratios in terms of the same amount of time.
For simplicity, lets see how many carrots each can make in 1 hour.


Janet can plant 36 feet of carrots in one hour

Amy can plant 34 feet of carrots in one hour
So, Janet can plant carrots more quickly
