Which of the following is not an algebraic tool required for simplifying the polynomial expression?

Mathematics

Answer:

Step-by-step explanation:

Let's simplify this expression first:

$Line1: 3x+3(2x+4)-8\\Line2: 3x+6x+12-8\\Line3: 9x+4\\$

In Line 2, we have used distributive property ( $a(b+c)=ab+ac$ ) and thus multiplication.
In Line 3, we have combined like terms

Choices A, B, and D can be eliminated as we have done those to simplify the expression.

Thus, "evaluation" -- choice C is the correct answer for this question.

Evaluation is when we plug in a specific value in the variables to find a "value/answer" of the expression given.

The figure below shows segments KL and MN which intersect at point P. Segment KM is parallel to segment LN:

DerKrebs [107]

Answer:

Angle KMP is congruent to angle LNP because they are alternate interior angles.

Step-by-step explanation:

Alternate interior angles are angles inside the parallel lines and on opposite sides of the transversal.

KM and NL are parallel to one another. KMP and LNP both fall between the parallel lines; this makes them interior.

KL is a transversal for the two parallel lines. KMP and LNP are on opposite sides of the transversal; this makes them alternate.

Therefore they are alternate interior angles.

Which fraction is equivalent to 2/5

My name is Ann [436]

Answer:

To make equivalent fractions, what we have to do is multiplicate or divide the numerator or denominator by the same number.

In our case:

$\frac{2}{5}=\frac{2*2}{5*2}=\frac{4}{10}$

$\frac{2}{5}=\frac{2*6}{5*6}=\frac{12}{30}$

$\frac{2}{5} = \frac{2*12}{5*12}=\frac{24}{60}$

That are only three examples, but there are infinite.

We could also obtain equivalent fractions dividing, for example, $\frac{3}{9}$ :

$\frac{3}{9}=\frac{\frac{3}{3}}{\frac{9}{3}}$ = $\frac{1}{3}$
