It is Prime and the only numbers that can go into it is 1 and 139.
It’s the last one. (X+2)2+(x+372-1/2)
The two numbers are 41 & 37.
The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know):
(x) + (x + 4) = 78
Now, we need to simplify it (combine like terms):
2x + 4 = 78
Then you can solve it like any other equation. Subtract 4 on both sides:
2x = 74
Divide by 2 on both sides:
x = 37.
So, now you know one number is equal to 37 and that the other is 37 + 4.
That's how you get 37 & 41.
42 red + 18 blue = 60 total.
Chance of red being pulled out once =
.
0.777... × 110 = 77 times.
You can expect the red paper to be pulled out 77 times.
