Answer:
3x2-3x+9
Step-by-step explanation:
(h-k)(3)
(X2+1-(x-2))(3)
(x2+1-x+2)(3)
3x2+3-3x+6
3x2-3x+9
Answer:
B.
Because the number of sides is 6 so the s go interior angles is 720. So if u want to get x u need to sum up the rest of the angles anf subtract from 720 giving an answer of 130
I think that whole numbers and natural numbers are the same set:- 1, 2, 3, 4 etc
Answer:
3x+2y=15--------(1)
4x+2y=20--------(2)
then, 2y=15-3x------(3)
putting value of 2y in equation (2)
4x+15-3x=20
x=5
then after , putting value of x in eq(3)
y=(15-15)/2
y=0
