I just did it on paper but hope that helps:)
2x^2 - 12x + 17
you just simplify it by doing the square number to the bracket and then multiply everything in the bracket by the number outside the bracket (this example 2)
<u>Answer-</u>
<em>The coordinates of the orthocenter of △JKL is (-4, 8)</em>
<u>Solution-</u>
The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side.
For a right angle triangle, the vertex at the right angle is the orthocentre of the triangle.
Here we are given the three vertices of the triangle are J(-4,-1), K(-4,8) and L(2,8)
If the triangle JKL satisfies Pythagoras Theorem, then triangle JKL will be a right angle triangle.
Applying distance formula we get,
As,
Therefore, the vertex at K (-4, 8) is the orthocentre.
Answer:
its 11/14 so its B hope this helps
Answer:
The answer is true because line f is seen on the plane R
