Answer:
x = (√2)/2
Step-by-step explanation:
The diagonal is √2 times the side length (x), so ...
1 = x√2
√2 = 2x . . . . . multiply by √2
(√2)/2 = x . . . . divide by 2
The side length x is (√2)/2.
120 miles = 3 hours
1mile = 3/120 = 1/40
200 miles = 1/40 times 200

Answer:
3x²+4x-2
Step-by-step explanation:
-
are not like terms. To make them like terms, you have to multiply the first fraction by 3x, and the second by 2.
This makes it 
-
, which can be expanded to 
-
.
This can be simplified to 
.
The numerator is therefore 3x²+4x-2.
