Answer:
5x^2+5x-1
Step-by-step explanation:
-2x^2+9x-3+7x^2-4x+2=5x^2+5x-1
First, find the value of x. Note that the angles x, 0.5x and 3x sum up to 4.5x, and that this sum has the value 180 degrees. Solving this equation for x, we get x = 40 degrees.
Now, 0.5x and 0.5y are vertical angles, and thus x = y. So, with x being 40 degrees, y = 40 degrees.

Answer:
1/6
Step-by-step explanation:
questions which include 'of 'usually means "×" (multiplication sign) so when u multiply them it gives 1/6
Answer:
c. x+4
Step-by-step explanation:
A graph shows zeros to be -2, 1, 3, 4. This means the factors will be ...
(x +2)(x -1)(x -3)(x -4)
The factor (x+4) is not among the factors of the given expression.
