Answer:
12
Step-by-step explanation:
The sum of the exterior and interior angles = 180°
let x be the measure of the exterior angle then interior angle is 5x and
5x + x = 180
6x = 180 ( divide both sides by 6 )
x = 30
The sum of the exterior angles of a polygon = 360°, thus
number of sides =
= 12
Answer:
The domain is all values but x=4 and x=2
Step-by-step explanation:
f(x) = (x+1) / ( x^2-6x+8)
Factor the function
f(x) = (x+1) / ( (x-4) ( x-2))
The domain of the function is all values of x except where the function does not exist
This is where the denominator goes to zero
(x-4) ( x-2) =0
Using the zero product property
x-4 =0 x-2 =0
x=4 x=2
The domain is all values but x=4 and x=2
Answer:
First one Equivalent but not simplified fully (Can combine the two y terms)
Second: Equivalent but not simplified fully (Can combine the two x^2 terms)
Third: Equivalent and simplified fully
Fourth: Not equivalent (y term is not correct)
Fifth: Not equivalent (x^2 term is not correct and the constant terms [ones without variables] can be combined)
Sixth: Not Equivalent (y term is not correct and the constant terms can be combined)
Step-by-step explanation:
You just need to know if two terms have the same variable they can be added or subtracted. But if it is say x and x^2 it cannot, they need to be brought to the same power as well. or if there is a term with xy, it can only be added and subtracted to other xy terms
Answer:
-45
Step-by-step explanation:
add 10 to -25, then divide 1/3 to that answer, which is -15. and you get -45
Just email your teacher and ask if you can raise your grade because you can’t do your work due to co-vid
