X2 is double the amount of x1
Easy so just Take 4.50 and I said by 1.50 which one you're going to get three more bags of three need times it by 108÷10 and then that will just be one box and then all you have to do is just find the other boxes with that number so
Answer:
Step-by-step explanation:
let the speed of one plane=x mph
speed of other plane=x+120 mph
x×1.5+(x+120)×1.5=1620
(x+x+120)×1.5=1620
(2x+120)×1.5=1620
3x+180=1620
3x=1620-180
3x=1440
x=480
speed of one plane=480 mph
speed of second plane=480+120=600 mph
The other factor of the polynomial which Sari is factoring and found that the one factor of this equation is (x+1) is (2x+3).
<h3>What is a factor of polynomial?</h3>
The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.
The polynomial which Sari is factoring is,
One factor of this equation is
Factor the given polynomial using the split the middle term method,

Answer:
The second one (answer of 3), but the other ones could've worked, they were just calculated wrong.
Step-by-step explanation:
Here's why each one did or didn't work:
First answer- you had the right idea by cancelling out the two in the denominator, however if you're going to divide 2, you have to divide it from everything in the equation. Meaning you would divide 4 by 2 to get 2, and then add the 1 + 2 to get final answer 3.
Second answer- since you added the numerator separately and then did the basic division, this worked.
Third one- similarly to the first one, you would have to also divide the 2 by 2 to get 1, then adding 1 + 2 to get 3.
