Answer:
x = 4
Step-by-step explanation:
The measures of all angles in this geometry are 90 degrees.
21x +6 = 90
21x = 84 . . . . . subtract 6
x = 4 . . . . . . . divide by 21

Answer:
y=x+8 and y=3x
Step-by-step explanation:
The Given point is (4,12)
now we can substitute the point in each of the function and check wether it lies on it or not.
A. y=x+8
substitute y=12,x=4
12=4+8=12 which is true
B. y=3x
substitute y=12,x=4
12=3*4=12 which is true
C. y=2x
substitute y=12,x=4
12=2*4=8 which is not true
D. y=x+6
substitute y=12,x=4
12=4+6=10 . which is not true
Therefore option A and B are correct.
