Provide the value of k: <br> (2x-1)(kx+1)=6x^2-x-1
guapka [62]

Answer:

k = 3

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms on both sides.

(2x - 1)(kx + 1) ← expand using FOIL

= 2kx² + 2x - kx - 1

Compare the coefficients of the x² term on both sides

2k = 6 ( divide both sides by 2 )

k = 3

Given: 4ABC, and BP is parallel to AC.<br> Prove: m21 + m22 + m23 = 180
Charra [1.4K]

Mathematical proofs are used to prove or disprove mathematical statements.

<h3>Mathematical theorems </h3>

The theorems to use are:

  • The sum of angles on a straight line is 180 degrees
  • Alternate angles are congruent

<h3>The proof</h3>

From the question, we have: \triangle ABC

This means that, ABC is a triangle

Also, we have:

BP || AC

This means that lines BP and AC are parallel

So, the following angles are congruent by alternate angle theorem

  • \angle 5 \cong \angle 3.
  • \angle 4 \cong \angle 2

The angles on a straight line add up to 180 degrees.

So, we have:

\angle 4 + \angle 1 + \angle 5 = 180

By substitution, the above equation becomes

\angle 2 + \angle 1 + \angle 3 = 180

Rewrite the equation as:

\angle 1 + \angle 2 + \angle 3 = 180

Hence, the statement that \angle 1 + \angle 2 + \angle 3 = 180 has been proved
