The other number is 18/y.
So, x + y = 42 and y - x = 5;
Then, y = x + 5;
Finally, x + x + 5 = 42;
2x + 5 = 42;
2x = 37;
x = 18.5;
y = 18.5 + 5;
y = 23.5;
Step-by-step explanation:
10 feet = 1 inch
50 feet = 5 inches
Do the same thing for the length.
If you don't under stand.
50/10 = 5
1/10 = x/50
10x = 50
x = 50/10
x = 5 inches
Then you do the same with the lenght.
FIRST section: x^2-3x+2 = x^2-x-2x+2=(x^2-x) -2x+2 = (x^2-x) -2(x-a million) = x(x-a million) -2(x-a million) = (x-2)(x-a million) 2nd section: x^-4 = x^2- 2^2 = (x-2)(x+2) So now your equation looks like this: FIRST section / 2nd section or (x-2)(x-a million) / (x-2)(x+2) and this comes out at (x-a million) / (x+2), so the respond is B.
No it should be 3,4,5 to make a right triangle
