Answer:
Yes, 12:18 is simplified to 2:3
Step-by-step explanation:
Answer:
Like terms:

1.25x²
-8x²
Step-by-step explanation:
Like terms are terms that have the same variable to the same exponent. In this case, the only like terms are those with the variable 'x' to the exponent of '2', or x². This would include the terms:

1.25x²
-8x²
The term 5yx², also includes x², however, it also includes the variable 'y' which makes it 'unlike' the other terms.
Answer:

Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), hence
F(- 1, 9) → F'(- 1, - 9)
G(- 2, 1) → G'(- 2, - 1)
H(- 7, 4) → H'(- 7, - 4)
Your answer is: 2x^6-x^4+5x^3+2x^2+1\x^2
Answer:
65
Step-by-step explanation:
Since these 115 and the angle adjacent to x are alternate interior angles, then that angle is equal to 115. That angle and x add up to 180, so we do 180-115, which is equal to 65.
