Answer:
x ≈ 14.87
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 10² + 11² = 100 + 121 = 221 ( take the square root of both sides )
x =
≈ 14.87 ( to the nearest hundredth )
The gcf of these two numbers is 1, because 189 and 200 don't have any common factors.
Its d) f(x)= 300+50x/2+x..............................................................................
I'm assuming you mean to list the terms of the expression. Those are mn, -2n, and +8. There are 3 terms there.
