Answer:
[tex]\huge\boxed{x=12}[/tex]
Step-by-step explanation:
If B is the midpoint of line AC, we know that lines AB and BC will be equivalent to each other.
Since we know the measures of AB and BC, we can just set these expressions equal to each other and find the value of [tex]x[/tex].
[tex]6x - 27 = 3(x+3)[/tex]
Let's simplify this equation until we have [tex]x[/tex] on one side of it.
[tex]6x-27=3x+9\\\\6x=3x+36\\\\3x=36\\\\x=12[/tex]
Hope this helped!

84 ft?
98 ft
Answers
Answer:
Option A
Step-by-step explanation:
If the length is twice as long as the width (14 ft), that makes it 28 ft. (14 x 2=28)
14 ft x 28 ft = 392 square feet
Therefore, the area of the solar cover is [tex]392[/tex] square feet. i.e., option (A) is the correct answer.

The formula for the volume of a cylinder is v=piR^2h where v is the volume, R is the radius, and h is the height solve the formula for R and then use it to answer the question.
A cylindrical bucket contains 615 cubic inches of water. The height of the water is 4 inches
What is the radius of the bucket, to the nearest whole number? Use 3.14 for pi
Answers
Answer: Its 6
Step-by-step explanation: The answer is 5.99894 then you round it to 6.
The radius of the bucket, to the nearest whole number, is 7 inches.
So, option A. is correct.
Here, we have,
To solve the formula v = πR²h for R, we can rearrange the equation as follows:
v = πR²h
R² = v / (πh)
R = √(v / (πh))
Given that the volume v is 615 cubic inches and the height h is 4 inches, we can substitute these values into the equation:
R = √(615 / (3.14 * 4))
Calculating the value, we have:
R ≈ √(48.98)
R ≈ 7
Therefore, the radius of the bucket, to the nearest whole number, is 7 inches.
Hence, So, option A. is correct.

1. A point is named or labeled using? 2. Three distinct points are collinear if ? 3. Three distinct points are coplanar if ? PLZ HELP
Answers
Answer:
1) A point P is named or labeled by using a coordinate pair, where the regular notation is:
P = (x, y).
Where x and y are the horizontal and vertical components.
2) Three distinct points are collinear if exists a line that passes through the 3 points.
3) Three distinct points are complanar if they are not collinear, this means that:
We can have two colinear points (so one line connects them) and another point outside that line.
Then the set of 3 points is coplanar.
