Answer: is a straight line that passes through the orgin hope it helps
Step-by-step explanation:
Answer:
78
Step-by-step explanation:
Solve by PEMDAS.
Parentheses first.
12-5 is 7 and 9x6 is 54, 83-54 is 29.
(7)^2+(29)
Exponent next,
49+29
add them up and you get 78.
Hope this helps! Hit the crown if you want.

Katie has equation 
and wants to solve it completing the perfect square. In order to do it, first rewrite 7 in right side:
Then note that 
so Katie has to add 
to both sides (because 
):
Answer: correct choice is C.
(x²+3x-4)(x-5)
x³-5²+3x²-15x-4x+20
x³-2x²-19x+20
Answer:
<EFC and <DCF
Step-by-step explanation:
Alternate interior angles: Angles that are inside the parallel lines and are opposite from each other
<DCA and <DCF are supplementary angles meaning they add up to 180 degrees.
<EFH and <GFC are vertical angles and both angles are not inside the parallel lines.
<BCF and <GFH are not alternate interior angles because both the angles aren't inside the parallel lines.
<EFC and <DCF are alternate interior angles because they are on opposite sides of the transversal and inside the parallel lines.
