Determine the factors of x^3 + 11^2-3x-33

Mathematics
1 answer:
notka56 [123]4 years ago
5 0

Answer:

(x²-3) and (x+11)

Step-by-step explanation:

The main method to find the factors of a polynomial is factoring.

To factor x³+11x²-3x-33 rewrite the expression as:

(x³+11x²)-(3x+33) and factor each piece individually:

To factor x³+11x² find the GCF (x²) and factor it out to find:

⇒ x²(x+11)

Next in 3x+33 the GCF is 3, factor to find:

⇒ 3(x+11)

And substitute both in the original expression to find that:

x³+11x²-3x-33=x²(x+11)-3(x+11)

And factor the GCF x+11:

⇒ (x²-3)(x+11)

And since these polynomials can be multiplied by each other to find the given polynomial they must be factors.

(48,-30) (61,-45) (74,-60) find the y intercept
sleet_krkn [62]

Answer:

The y-intercept is about  25.385

Step-by-step explanation:

Calculate slope from difference in  y-values divided by difference in x-values.

-15/13 is slope.

Use slope-intercept form.

Y= mx + b

Substitute values from given coordinates for y and x, then solve for b

-60 = -15/13(74) + b

-60 = -85.385 + b

-60 +85.385 = b

25.385 = b

If you chose an angle, how are the construction steps you completed similar to the steps you would have taken to construct and b
valentinak56 [21]

There are different ways to construct an angle. The steps used in making a line segment are; First, you have to put the compass at one specific end of the line segment. Then you shift the compass slowly a little bit so it will be longer than half the length of the line segment. Then you have to draw arcs up and down the line. while using the same compass width, you then draw arcs from one specific end of the line. and thereafter you put your ruler at the point where the arcs cross, and you then draw the line segment. The difference is that to bisect an angle, one has to divide the shape or angle into two congruent parts while in the construction of a line segment, there are differences in length. What is the construction process of Angles? This entails a good construction process in making angles. They are step-by-step processes used to produce detailed and exact geometric figures.

3. Evaluate the expression. If k = 3 and h = 2. (Be sure to show each step)<br> 4k+2(5k-2)-h
faltersainse [42]

Answer:

36

Step-by-step explanation:

Simple:

(4)(3)+2((5)(3)−2)−2

=12+2((5)(3)−2)−2

=12+2(15−2)−2

=12+(2)(13)−2

=12+26−2

=38−2

=36
