Answer:
so where are the 3 consecutive numbers?
Answer:
x-5+ 
Step-by-step explanation:
If x+2 is a factor, -2 is a zero. So we can put -2 in the left-hand corner of your synthetic division, bring the coefficients down so you'll have a set up like this:
-2 | 1 -3 -7
____________
1. bring down the 1:
-2 | 1 -3 -7
____________
1
2. multiply that by -2 and enter the result underneath 3:
-2 | 1 -3 -7
-2
___________
1
a. then, add through:
-2 | 1 -3 -7
-2
___________
1 -5
3. Do the same for -5 (multiply by the zero -2), enter that underneath -7 and add through:
-2 | 1 -3 -7
-2 10
___________
1 -5 3
Now, reassign the coefficients to their x. Because we already factored out an x with the zero, the 1 is assigned to 'x' rather than back to '
'. The '-5' will not have an x attached. '3' is your remainder and cannot be divided out any further, so it will be written as
. Finally, just put them back together to get x-5+

Hope this helped!
Answer:
2.2 more kg
Step-by-step explanation:
0.8+3.95=4.75
6.95-4.75=2.2
hope I helped!!
X1=-15
X2=-1
I think this is the answer
