Answer:
-7
Step-by-step explanation:
Because there is no multiplication, it is just the x^2 terms. There is a -(-2x^2) and a -9x^2, so it is 2x^2 and -9x^2 or -7x^2, so the coefficient is -7.
Answer:
The answer is -38
Step-by-step explanation:
Hello
from the first interval you’re given, you can see the slope is 1, and if you were to extend that line you would get the y-intercept to be 3
the second interval given you can see that every point will have the y-value as 5
so for your first blank it should be x+3 and your second blank should be 5
hope this helps
let me know if you got confused on anything and i will do my best to help
have a nice day :)

Answer:
33 inches
Step-by-step explanation:
In a quadrilateral ABCD, AB ∥ DC and AD ∥ BC.
AC = 20 in, BD = 20 in, AB = 13 in.
We want to find the perimeter of ΔCOD if point O is the intersection of the diagonals.
Since AB ∥ DC and AD ∥ BC, the point O divides the diagonals into two equal parts.
|OD|=|BD|/2 = 20/2 =10inch
Similarly,
|OC|=|AC|/2 = 20/2 =10inch
Also,
AB=CD=13 inch
Therefore,
Perimeter of ΔCOD= |OD|+|OC|+|CD|
=10+10+13
=33 inches
