-x^2-x+y-6 Should be right
y=x^2-x-6 = x^2-x+y-6
That is true because if you use the surface area formula, 2(wl+hl+hw), you'll get 250.
Answer:
She gets
Step-by-step explanation:
She gets an error message because when solving a linear equation, the coefficient of the variable is not meant to be the same on both sides of the equation because it will equal 0 in the end. In this equation, you will get 4x on both sides and then the last step will be 0= 3. This is an error.
