Answer:
B. 2x^2 -5x +2y
Step-by-step explanation:
Substitute the given expressions and collect terms.
g(x) -f(x)
= (2x^2 -3x +6y) -(2x +4y)
= 2x^2 -3x +6y -2x -4y
= 2x^2 -5x +2y . . . . . . . . . . matches choice B
Answer:
x = 5
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 + 9² = 16²
x² + 81 = 256 ( subtract 81 from both sides )
x² = 175 ( take the square root of both sides )
x = 
= 5 ≈ 13.23 units ( to 2 dec. places )
Answer: 80% or 4/5
Step-by-step explanation:
so I don’t know how many numbers there are on this cube (a standard number cube has #1-6) but I’m going to go with 10 numbers (don’t know how this is possible but anyway-). I’ll edit my answer if needed.
10 numbers
10 (numbers) - 2 (#8 and #10) = 8 (possible numbers)
so 8/10 or 80%
reduced fraction: 4/5
percentage: 80%
fraction: 8/10
