Which expression is equivalent to (2x^2+3)(x+4) ?

Answers

Answer 1

Answer:

2 x^3+ 8 x^ 2 + 3 x + 12

Step-by-step explanation:

Answer 2

Answer:

2x³ + 8x² + 3x + 12

Step-by-step explanation:

Given

(2x² + 3)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

2x²(x + 4) + 3(x + 4) ← distribute parenthesis

= 2x³ + 8x² + 3x + 12

Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.

Answers

Answer:

y = 3/5x - 17/5

Step-by-step explanation:

slope formula: (y₂ - y₁) / (x₂ - x₁)

First, plug in these values of the two given points.

(-4 - (-1)) / (-1 - 4)

Simplify within the parentheses.

(-4 + 1) / (-1 - 4)

(-3) / (-5)

3/5

This is your slope. Plug this into a standard slope-intercept equation: y = mx + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.

-4 = 3/5(-1) + b

Multiply.

-4 = -3/5 + b

Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.

-20/5 = -3/5 + b

-20/5 + 3/5 = b

-17/5 = b

Now, plug this into your standard equation.

y = 3/5x - 17/5

Check this equation by plugging in the other point you did not use (4, -1)

-1 = 3/5(4) - 17/5

-1 = 12/5 - 17/5

-1 = -5/5

-1 = -1

Your answer is correct!

Hope this helps!

If a point, ray, line, line segment, or plane intersects a segment at its midpoint, then it is?

Answers

Answer:

If A Point, Ray, Line Segment, or Plane intersects a segment at its midpoint, then it Bisects the segment.

Step-by-step explanation:A segment, ray, line, or plane that is perpendicular to a segment at its midpoint is called a perpendicular bisector. If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. Point is equidistant from two points if its distance from each point is the same.

The volume of a sphere is two-thirds of a cylinder. What is the volume of a cylinder that has the same diameter as a sphere with a volume of 14 u^3, in u^3

Answers

Answer:

[tex]V_2= \frac{28}{3} u^3[/tex]

Step-by-step explanation:

Given

Represent the volume of the cylinder with V1 and the volume of the sphere with V2

So, from the first statement: we have:

[tex]V_2 =\frac{2}{3}V_1[/tex]

and

[tex]V_1 = 14u^3[/tex]

To solve for [tex]V_2[/tex], we simply substitute [tex]14u^3[/tex] for [tex]V_1[/tex] in [tex]V_2 =\frac{2}{3}V_1[/tex]

[tex]V_2 =\frac{2}{3}V_1[/tex]

[tex]V_2= \frac{2}{3} * 14u^3[/tex]

[tex]V_2= \frac{2* 14}{3} u^3[/tex]

[tex]V_2= \frac{28}{3} u^3[/tex]

Hence, the volume of the sphere is [tex]\frac{28}{3} u^3[/tex]

Answers

Answer:

x=2

Step-by-step explanation:

Simplify both sides of the equation.

2x−1−(−x + 3)=6−2x

(Distribute the Negative Sign)

2x−1 + −1(−x + 3)=6−2x

2x + −1 + −1(−x) + (−1)(3)=6−2x

2x + −1 + x + −3=6−2x

2x + −1 + x + −3=6 + −2x

(Combine Like Terms)

(2x + x) + (−1 + −3)=−2x+6

3x + −4=−2x + 6

3x−4=−2x + 6

Add 2x to both sides.

3x−4 + 2x=−2x + 6 + 2x

5x−4=6

Add 4 to both sides.

5x−4 + 4=6 + 4

5x=10

Divide both sides by 5.

5x/5=10/5

What is a quadrilateral?

A quadrilateral is a plane figure with four edges and four corners, also known as vertices. The quadrilateral's four vertices or corners all have angles. A quadrilateral has four straight sides and is a two-dimensional shape. Parallelograms, trapezoids, rectangles, kites, squares, and rhombuses are a few examples of quadrilaterals.

A quadrilateral with four equal sides and angles is called a square. Due to its equal sides and angles, it is also a regular quadrilateral. A square has four 90° angles, just like a rectangle does. It can also be thought of as a rectangle with equal lengths on its two adjacent sides. A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral.
