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
