There are two questions :v
Answer:
Step-by-step explanation:
One
v^2 - 16
This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.
The square root of v^2 = v
The square root of 16 = 4
You get (v + 4)(v - 4)
Let's see what happens when you expand it.
v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16Look what happens when you add these 4 terms together.
v^2 - 4v + 4v - 16v^2 - 16is what is left. The two middle terms cancel out.
Two
This one is a perfect square
w^2 + 16w + 64
(w + 8)(w + 8)
Notice both factors are the same. You might wonder how I new that.
w^2 is a perfect square so take the square root. .... v
64 is a perfect square so take the square root ..... 8
Now you have to work backwards to see if it is right.
w*w = w^2w*8 = 8w8*w = 8w8^2 = 64Adding you get w^2 + 16w + 64 which is what you started with.

If the endpoints of the diameter of a circle are (6, -2)and (-6 ,2)what is the standard form equation of the circle
Answer:
[tex]x^2 + y^2 - 40 = 0[/tex]
Step-by-step explanation:
Given
[tex](h_1,k_1) = (6,-2)[/tex]
[tex](h_2,k_2) = (-6,2)[/tex]
Required
Determine the equation of the circle
First, calculate the midpoint of the given coordinates:
[tex](h,k) = \frac{1}{2}(h_1+h_2,k_1+k_2)[/tex]
[tex](h,k) = \frac{1}{2}(6-6,-2+2)[/tex]
[tex](h,k) = \frac{1}{2}(0,0)[/tex]
[tex](h,k) = (0,0)[/tex]
Next, calculate the radius.
This is the distance between [tex](0,0)[/tex] calculated above and any of [tex](6,-2)[/tex] [tex](-6,2)[/tex]
Using:
[tex](0,0)[/tex] and [tex](-6,2)[/tex], the radius is:
[tex]r = \sqrt{(0 - (-6))^2 + (0-2)^2}[/tex]
[tex]r = \sqrt{40}[/tex]
The equation is then calculated using:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
Where:
[tex]r = \sqrt{40}[/tex] and [tex](h,k) = (0,0)[/tex]
[tex](x - 0)^2 + (y - 0)^2 = (\sqrt{40})^2[/tex]
[tex](x )^2 + (y)^2 = 40[/tex]
[tex]x^2 + y^2 = 40[/tex]
[tex]x^2 + y^2 - 40 = 0[/tex]

Answer:
4 inches
Step-by-step explanation:
To solve this, use the Pythagorean Theorem: a² + b² = c². You insert the measurements you have: 3² + b² = 5² or 9 + b² = 25. To solve this, subtract 9 from both sides: b² = 16. To solve for b (length) specifically, find the square root of 16: 4.

Find the area of the shaded region. Use 3.14 for pi.
Answer:
326
Step-by-step explanation:
First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.
Solve this equation:
7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)
Answer:
x = 7/5
I hope this helps
Step-by-step explanation:
7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)
7x - 5 -3x +2 = x -4x +5 +2x -1
4x -3 = -x +4
4x +x = 4+3
5x = 7
x = 7/5

Step-by-step explanation:
We presume the first transformation is a translation 4 units right and 1 unit up:
(x, y) ⇒ (x+4, y+1)
The second transformation negates the x-coordinate, so the two transformations together have the rule ...
(x, y) ⇒ (-(x+4), y+1)

A video game box is 15 inches long and 10
inches wide. If the volume of the box is 750
cubic inches, how tall is the box?
in inches
Answer:
The box is 5 inches tall
Step-by-step explanation:
The given dimensions of the video games are;
The length of the video game, L = 15 inches
The width of the video game, W = 10 inches
The volume of the video game box, V = 750 cubic inches
Assuming that the shape of the video game box is a cuboid, we have;
The formula for the volume of a cuboid, V = Length, L × Width, W × Height, H
∴ V = L × W × H
The height of the cuboid, H = V/(L × W)...(1)
Where, for the video game box;
L = Length = 15 in.
W = Width = 10 in.
V = Volume = 750 in.³
Plugging in the values of the variables in equation (1) gives;
H = V/(L × W) = 750 in.³/(15 in. × 10 in.) = 5 in.
The height of the box, H = 5 inches.

43.8% complete This is a Single Choice Question; skip ahead to question content A B C D E Confirm To order the right amount of flooring, you need to know the floor area of the living room shown below. What is that area, in square feet?
Answer: 180 ft²
Step-by-step explanation:
The rest of the question is:
The living room is 18 feet wide and 10 feet long.
The floor seems to take the shape of a rectangle because it has one dimension being longer than the other.
As this is a rectangle, the floor area will be calculated by the formula:
= Length * Width
= 10 * 18
= 180 ft²
