What is the area of this quadrilateral(Please show a step by step process)
Answer:
40ft
Step-by-step explanation:
What you need to know is the formula for the air of a rectangle:
the long side * the short side.
First calculate the area of the rectangle in the middle: 3*8=24ft
Then we are left with two right-angled triangles, one on the left and one on the right. If we juxtapose them, we realize that it forms a rectangle whose large side measures 8 and the small 2 so 2*8=16ft.
Finally, just add the area of the middle rectangle with the area of our rectangle formed by the two triangles on the right and on the left. So 16+24=40ft

x = –8 –6x + 9y = 12 solve for substitution
Answer:
x= -8,y= -4
Step-by-step explanation:
Substitute x= -8
-6(-8)+9y=12
simplify
48+9y=12
isolate for y
y= -4
The solutions to the system of equations are:
x= -8 and y= -4

What is the space between two intersecting lines called?.
Answer:
The space between two intersecting lines is called an:
Angle
An angle is formed when two lines meet at a shared point. They are measured in degrees. There are four important types of angle; acute, right, obtuse, and reflex. A full circle has 360 degrees. If you see an angle of 720 degrees, it means it has rotated twice around a full circle.
360 degrees (one time round) x 2 = 720 degrees (two times round)

The volume of the square base pyramid is 588 ft³
The Volume of the rectangular prism is 120 ft³
The Volume of a rectangular pyramid is 360 ft³
What is volume of a shape?Volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object.
Volume of a square base pyramid = 1 / 3 × B × h
where
B = base area
Therefore,
Volume of a square base pyramid = 1 / 3 × 7² × 12
Volume of a square base pyramid = 1764 / 3 = 588 ft³
Volume of a rectangular prism = lwh
Volume of a rectangular prism = 6 × 5 × 4 = 120 ft³
Volume of a rectangular pyramid = 1 / 3 lwh
Volume of a rectangular pyramid = 1 / 3 × 10 × 12 × 9 = 1080 / 3 = 360 ft³

What is a line? What is an angle? How do you describe a line and an angle? How do we know if an angle is right? obtuse? acute? or a full circle?
Answer:
A line is something that goes on endlessly in both directions. An angle is the number of degrees at a point where two rays meet. We know if an angle is right if there is a right angle that measures up to 90°. An obtuse is any angle that measures over 90° and an acute angle is under 90°. Hope this helps! :)

2x-10=12 what is the value of x+4
Answer:
15
Step-by-step explanation:
if 2x-10=12 then
2x=22 so
X=11
X+4= 15
Answer:
15
Step-by-step explanation:
1. we find what x is by finding out the first equation:
2x - 10 = 12
Add 10 to both sides (it cancels out on the first side)
-10 + 10 = 0 (cancels out)
12 + 10 = 22
2x = 22
Now we divide both sides by 2 to get x alone
22 divided by 2 = 11
X = 11
2. Now we can solve the equation x + 4:
Just fill in x, which as we solved, is 11
x + 4 = 11 + 4 = 15
Therefore, the value of x + 4 is 15.

What is a Hemisphere?A hemishpere is half of a sphere. Thus, two hemispheres makes one full sphere.
Given the image as shown below, since the identical hemispheral holes are centered at the center of each fce and they touch each other at only one point, it means that two hemisphere meet to make one full sphere.

so if you look at the bottom left corner you can see 1 box is the same as saying for every second someone walks its one metre.
thats not how i got the answer though.
if you look at the starting point at 8 because she was 8 meters away you need to see when she comes across her first second which after 2 meters (Goes down two squares before reaching the first second)
now technically soe of the other answers are correct too but heres how i thought about it.
A. its correct but i dont think that's what its asking you for tbh
B. This we don't know for sure. eg she could take 890 seconds walking back to her starting point we just don't know for sure.
C. This is also true but once again it's easily given to you so i dont think that's what you're being asked.

Natoshia's den is 4 feet longer than it is wide. If the den's area is 320 square feet, what are the dimensions of the room?
Dimensions : 16 x 20
Let the width be xthen the length: x + 4 area of rectangle = Length * Widthsolving steps:
(x+4)(x) = 320x² + 4x = 320x² + 4x - 320 = 0x² +20x -16x -320 = 0x(x + 20) -16(x+20) = 0(x-16)(x+20) = 0x = 16, -20x = 16 [ As length or width can never be negative ]So we found Width = 16 feet
Length:
16 + 420 feetAnswer:
width = 16 ft
length = 20 ft
Step-by-step explanation:
Let width = x
If the length is 4 ft longer than the width, then
⇒ length = x + 4
Area of a rectangle = width × length
Given:
area = 320width = xlength = x + 4Substituting these values into the equation for the area of a rectangle and solving for x:
⇒ 320 = x(x + 4)
⇒ 320 = x² + 4x
⇒ x² + 4x - 320 = 0
⇒ (x - 16)(x + 20) = 0
⇒ x = 16, -20
As distance is positive, then x = 16 only.
Therefore, width = 16 ft and length = 20 ft
