Answer please
The figure below shows a quadrilateral ABCD. Sides AB and DC are congruent and parallel:

A quadrilateral ABCD is shown with the opposite sides AB and DC shown parallel and equal.

A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram:

Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent. Side AB is equal to side DC, and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by SSS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel.

Which statement best describes a flaw in the student's proof?

Question 11 options:

Angle DBC and angle BDA form a pair of vertical angles, not a pair of alternate interior angles, which are congruent.


Triangles ABD and CDB are congruent by the SAS postulate instead of the SSS postulate.


Triangles ABD and BCD are congruent by the AAS postulate instead of the SSS postulate.


Angle DBC and angle BDA form a pair of corresponding angles, not a pair of alternate interior angles, which are congruent.

Answer: It depends, some are easier as words, and some are easier as written problems.

Answer:

A, B, C, E, F.

Step-by-step explanation:

320 / 8 = 40

So the length times the  height of the prism  will be 40.

So the possible dimensions are

A ( 4 * 10).

B.

C.

E.

F

The option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

We have volume of rectangular prism = 320 cubic unit

Width of the rectangular prism = 8 unit

320 = l×w×h

320 = 8l×h

l×h = 40

So the multiplication of the length and height should be 40

A. 4 unit cubes long and 10 unit cubes high:

l×h = 4×10 = 40

B. 5 unit cubes long and 8 unit cubes high:

l×h = 5×8 = 40

C. 8 unit cubes long and 5 unit cubes high:

l×h = 8×5 = 40

D. 8 unit cubes long and 8 unit cubes high:

l×h = 8×8 = 64

E. 10 unit cubes long and 4 unit cubes high:

l×h = 10×4 = 40

F. 20 unit cubes long and 2 unit cubes high:

l×h = 20×2 = 40

G. 20 unit cubes long and 20 unit cubes high:

l×h = 20×20 = 400

H. 25 unit cubes long and 15 unit cubes high:

l×h = 25×15 = 375

Thus, the option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.

Answer:

x≥5

Step-by-step explanation:

Let's solve your inequality step-by-step.

5≤−5+2x

Step 1: Simplify both sides of the inequality.

5≤2x−5

Step 2: Flip the equation.

2x−5≥5

Step 3: Add 5 to both sides.

2x−5+5≥5+5

2x≥10

Step 4: Divide both sides by 2.

2x/2 ≥ 10/2

x≥5

Answer:

Answer:

x = 9/4

Step-by-step explanation:

Solve for x.  Start by adding 6x to both sides, which results in 3 + 4x = 12.

Combine the constants, obtaining 4x = 9.

Dividing both sides by 4, we get x = 9/4.

Answer:

  S

Step-by-step explanation:

The distributive property is used for this purpose. I find it easier to distribute the shorter factor.

  [tex](2x^2-4xy+2y^2)(3x-4)\\\\=(3x)(2x^2-4xy+2y^2)-(4)(2x^2-4xy+2y^2)\\\\=6x^3-12x^2y+6xy^2-8x^2+16xy-8y^2\quad\text{matches choice S)}[/tex]

The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.

If you were to solve the equation it would look like this:

2x+6=3x-8

-3x -3x

-x+6=-8

-6 -6

-x=-14

/-1 /-1

x=14

Answer:

2x

Step-by-step explanation:

Diego subtracted 2x from the left side which gave him 6 and subtracted 2x from the right side of the equation to get x-8

Answer:

Distribute the 6 to the terms inside the parentheses.

5=6q-30-19

Combine like terms.

5=6q-49

Add 49 to both sides.

54=6q

Divide both sides by 6.

q=9

Domain: all real numbers

Graph is below.

====================================================

Explanation:

This is a piecewise function that is composed of two parts:

This piecewise function has split identities or multiple aliases so to speak. It all depends on what the x input is.

The graph is shown below.

The domain is the set of all real numbers since any x value will lead to some y output. Even x = 0 itself is allowed. Note the arrows indicate the graph stretches on forever to the left and to the right.

The range on the other hand isn't all real numbers. Instead, it's [tex]y \le 6[/tex] indicating that y = 6 is the largest y can get. Simply locate the highest point on the graph (similar to the concept of the vertex) and you'll spot the highest y value.

The amount of calories per ounce does the steak have is 75 calories per ounce.

Using this formula

Calories per ounce=Total calories/Number of oz sirloin steak

Where:

Total calories=1,800 calories

Number of oz sirloin steak=24 oz

Let plug in the formula

Calories per ounce=1800/24 oz

Calories per ounce=75 calories per ounce

Inconclusion the amount of calories per ounce does the steak have is 75 calories per ounce.

Answer:

Ur reatarded

Step-by-step explanation:

Recall that

cos²(t) + sin²(t) = 1

Then solving for cos(t) and sin(t), we have

x = 3 cos(t)   ===>   cos(t) = x/3

y = -6 sin(t)   ===>   sin(t) = -y/6

so that the above identity gives us

(x/3)² + (-y/6)² = 1

x²/9 + y²/36 = 1

36 (x²/9 + y²/36) = 36

(C) 4x² + y² = 36

The parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.

We have two parametric equations:

x = 3cos(t) and

y = -6sin(t).

As we know, the trigonometric identity:

sin²θ + cos²θ = 1

For checking the option (A):
2x² + y² = 36

= 2(3cos(t))² + (-6sin(t))²

= 18cos²t + 36sin²t ≠ 36

Similarly, for checking the option:

4x² + y² = 36

= 4(3cost)² + (-6sint)²

= 36cos²t + 36sin²t

= 36(cos²t + sin²t)

= 36(1) = 36

Thus, the parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).
