D x= -9
Y=9
Because 4(-9)+45=9
I just put in each one and d got it right.
Alright, so since anything can be squared, the domain is (-inf, inf)
n=9 would be your answer. Hope I helped
DO NOT LISTEN TO THE OTHER PERSON, you can CLEARLY see thats not the right answer. She/He is bluffing.
The true answer:
The shape has 4 faces. Faces means the sides of a 3d figure/the sides are the 2d shapes that form together to form one 3d figure. Btw that figure is a triangular pyramid.
Com.ment me if u have any questions
Have a nice day!
The name of the angle is obtuse
