Option D is correct

2x^3 - 7x^2 + 4x - 3

Step-by-step explanation:

= x(2x^2 - x + 1) -3 (2x^2 - x + 1)

= 2x^3 - x^2 + x - 6x^2 + 3x - 3

= 2x^3 - x^2 - 6x^2 + x + 3x - 3

= 2x^3 -7x^2 + 4x -3 (Ans)

Answer: 7(b-1)^2-63

Step-by-step explanation:

Factor out 7

7(b^2-2b-8)

Add and subtract (-1)^2:

7(b^2-2b-8+(-1)^2-(-1\)^2)

Complete the square:

7((b-1)^2-8-(-1)^2)

Simplify:

7(b-1)^2-63

Answer:

2 1/2

Step-by-step explanation:

When multiplying fractions, you multiply the numerators together and the denominators together.

4 • 5/8

Multiply 4 and 5.

20/8

You can simplify this by dividing both parts by 4

5/2

5/2 is also 2.5

2.5 written as a mixed number is 2 1/2.

This is your answer.

Hope this helps!

Answer:

Any elements that are in either H or W will be in the union of the sets

Step-by-step explanation:

Anytime that is asking for the union of two sets with the symbol (U) than it is asking you to figure out what elements are in either one of the two sets.

That means the Union would be in either set.

Therefore (Any elements that are in either H or W will be in the union of the sets)

Answer:

y = -2/3x + 5

Step-by-step explanation:

Find the slope by doing change in y / change in x:

-1 / 1.5 = -2/3

Then, put the equation in point slope form:

y - 5 = -2/3(x - 0)

y - 5 = -2/3x

y = -2/3x + 5

Answer:

x = [tex]\frac{85}{3}[/tex]

Step-by-step explanation:

From the figure attached,

ΔABC ~ ΔADE

Therefore, by the property of similar triangles corresponding sides of the given triangles will be proportional.

[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]

[tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]

[tex]\frac{12}{20}=\frac{17}{x}[/tex]

x = [tex]\frac{20\times 17}{12}[/tex]

x = [tex]\frac{85}{3}[/tex]

Answer:

x = 17

Step-by-step explanation:

number of sides (n) = 5

Sum of angles of polygon = (n - 2) *180

                                            = 3 * 180 = 540

9x + 71 + 92 + 5x + 139 = 540

9x +5x + 71 + 92 + 139 = 540

                   14x + 302   = 540

                               14x  = 540 - 302

                                14x = 238

                                    x = 238/14

x = 17

a number can be written a "x".

"minus" is a key word for subtraction.

"is" is a key word for =.

So if we put that all together, we have

x-3=5

To solve it, we have to add 3, to cancel it out, and add 3 to 5.

x-3=5

+3 +3

x=8

Step-by-step explanation:

5a + 5b - 5 + 11a - 11b + 11 = 5a + 11a + 5b - 11b - 5 + 11 = 16a - 6b + 6

Answer: B

Step-by-step explanation:

Answer:

The answer is 15

Step-by-step explanation:

Simply because it’s asking for the length ON BOTH SIDES so it’s a triangle and on the top of the triangle is a D than the 2 other ends are S and A

Why do this?

Because we want to be able to factor the left hand side into the form p^2, where p is some algebraic expression. This will help us ultimately solve for x.

Currently, the left hand side is x^2+16x which does factor to x(x+16), but that isn't in the form p^2. We want something like (x+1)^2 or (x+2)^2. The general form is (x+k)^2 where k is some fixed constant.

Let's expand out (x+k)^2 using the FOIL rule and we get x^2+2kx+k^2

The x coefficient is 2k. If we cut that in half, we get k. Squaring that result leads to k^2.

So we have this order: 2k cuts in half to k then square it to get k^2

For x^2+16x, we have the x coefficient as 16. That cuts in half to 8, then that squares to 64. We add 64 to both sides

Note how

x^2+16x = 9

x^2 + 16x + 64 = 9+64

(x+8)^2 = 73

From here, we apply the square root to both sides and then subtract 8 from both sides to fully isolate x. You would get two different solutions.

-------------

I recommend you use the FOIL rule to confirm that (x+8)^2 expands out to x^2+16x+64, to help check your work.

They have to sell D. 75 shirts to make a profit of $300.

The total cost of buying and printing the shirts was $600.

In order to make a profit of $300, they would therefore have to raise:

= Cost + profit

= 600 + 300

= $900

As they are selling each shirt $12, the number of shirts they would have to sell to get to $900 is:

= 900 / 12

= 75 shirts

They would therefore have to sell 75 shirts in order to make a profit of $300.

Step-by-step explanation:

a cone with a pyramid with equal base areas and height

Cavalieri's principle tells us about the volume of two shapes. The correct option is a cylinder and a right rectangular prism with equal heights.

According to Cavalieri's principle if two objects have the same height and same base area throughout their heights, then the volume of both objects would be the same.

As we know according to Cavalieri’s Principle, the object should have the same height. Also, the area of the object should be the same throughout the height, but since in a cone the area is gradually decreasing towards the top, and the area of the sphere is also decreasing about the top and the bottom of the sphere. therefore, the options with the object such as cone and sphere are not the correct options.

Thus, the correct option is a cylinder and a right rectangular prism with equal heights as shown in the below image.
