I think this is the answer to what u r trying to say: so u would take one domino ex.) top:5 bottom: 8. u would match that with true sentences by doing the top number plus the bottom number. ex.) 5 + 8 = 13.
1) m-5= -18 (add 5 to both sides)
m= -13
2) m-11= -4 (add 11 to both sides)
m= 7
3) x+10=22 (subtract 10 from both sides)
x= 12
4) n-19= -16 (add 19 to both sides)
n= 3
12a + 8
4(3a +2)
12a + 2
4(3a + 8)
12a + 8
Your answer is B) 4(3a + 8)
Hope this Helps!!

Answer:
f(h(x)) = x
h(f(x)) = x
Step-by-step explanation:
f(x) = 8x-7
h(x) = x+7/8
We need to find f(h(x)) and h(f(x))
Finding f(h(x))
Putting value of h(x) into f(x) i.e
f(h(x)) = 8(x+7/8)-7
f(h(x)) = x+7-7
f(h(x)) = x
Now finding h(f(x))
h(f(x)) = (8x-7)+7/8
h(f(x)) = 8x-7+7/8
h(f(x)) = 8x/8
h(f(x)) = x
