Step-by-step explanation:
3^2*2-4(3-1)
3^2=9
9*2
9×2
18
4(3-1)
4(2)
8
18-8
=10
So the final answer is 10
The reflection about x-axis results in same x coodinate with oppositive of y coordinate. It can be expressed as,
Determine the coordinates of the vertices after reflection over the x-axis.
-2x-2y-2z I think that is answer
1A. C B E D A F
B. H G J K I L
3x + 122 = 22x - 11
+11 + 11
3x + 133 = 22x
-3x -3x
133 = 19x
x = 7
