Answer:
answer is c of your question
Let the number be xy ,
xy = 10x + y. when reversed = yx = 10y + x
x = 2y ........(a)
10x + y + 10y + x = 66.........(b)
10(2y) + y + 10y + 2y = 66
20y + y + 10y + 2y = 66
33y = 66
y = 66/33
y = 2
x = 2y = 2*2 = 4
Recall the original number is xy = 42.
The answer would be false because the number .8 can be 8/10 but it is rational and you can understand that. It would not be an irrational number.
Answer:
its c hope it helps not totally sure but yeah
Step-by-step explanation:
Set both expressions equal to 0
x-3=0
x=3
2x-8=0
2x=8
x=4
your zeroes are 3 and 4
