Answer:
Answer: Third option is the right answer.
Step-by-step explanation:
First we the write the expression

Now teacher says that the product of these polynomials will result in the sum of 
Now the teacher ask if we put the value of a = 2x and b = 1 then what will be the expression look like.
![(2x+1)\left [ (2x)^{2}+(1^{2})-(2x)(1)\right ]](https://tex.z-dn.net/?f=%282x%2B1%29%5Cleft%20%5B%20%282x%29%5E%7B2%7D%2B%281%5E%7B2%7D%29-%282x%29%281%29%5Cright%20%5D)
=
So third option is looking like our expression.
Answer:
5x+9y=-16
Step-by-step explanation:
here is my work although I am not 100 percent sure I am right because,I am learning the same thing as you
-6+1 over 4+5
y+1=-5/9(x+5)
y+1=-5/9x-25/9
y=-5/9x-16/9
5/9+y=-16/9
5x+9y=-16

Step-by-step explanation:822.73
Answer:
162.5mi
Step-by-step explanation:
If the scale of the map is 1in:25mi, and you measure 6.5in between two twoms, then the real distance would be 6.5in*25mi = 162.5mi.
Since these both are on the same hour we'll ignore the 5. We end up having :35 and :52. We'll subtract 35 from 52 which gives us 17. The answer to this is 17 minutes.
