The diagram shows the plans for the triangular
park. How much longer is BC than AC?
(3x2 – 25x – 12) feet
(3x2 - 5x - 12) feet
(3x2 + 5x – 4) feet
(3x2 + 25x – 4) feet
(10x + 3x2 - 8) ft
(12x) ft

(3x2 - 5x - 12) feet

Step-by-step explanation:

(10x + 3x2 - 8) - (15x + 4)

(10x + 3x2 - 8) + (-15x - 4)

(3x2) + (10x - 15x) + (-8 - 4)

(3x2 - 5x - 12)

B.(3x2 - 5x - 12) feet

Just took it. Edg 2020. Hope this helps :)

Can i get a brainliest plz? Thx.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
