Answer:
its 18 because, 8+4=12 divided by 2=6x3=18
I'm in Connexus too btw :)
Step-by-step explanation:
Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
Did you forget an “x” on the 12^4 ? Because if you didn’t, then the answer would be: 3x^4 + 12^4 -2x^3 + x^2 - 10, but if you did, then it would be the picture.
