The answer is the third answer choice.
For this question, we can use proportional reasoning to find out the answer.
Let us call the point at the other end of line and in between the two expressions, D.
Side AB:AC = BD:DC (remember that ratios are the same as division so you can do the exact same thing with division statements instead).
Now substitute: 8:12 = (x+4):(2x+1).
Now solve (if using division instead of ratios, solve regularily for x):
8:12 = (x+4):(2x+1),
8(2x+1) = 12(x+4),
16x+8 = 12x+48,
16x-12x = 48-8,
4x = 40,
x = 10.
Therefore x = 10
Answer:
X = 2

Answer:
0.04671
Step-by-step explanation:
Basically, add a number smaller than 0.0001
The volume of the solid generated when the right triangle below is rotated about side is 564.2.
<h3>How to calculate the volume?</h3>
The volume will be calculated by using the formula:
= 1/3πr²h
where, r = 7
h = 11
Therefore, the volume will be:
= 1/3πr²h
= 1/3 × 3.14 × 7² × 11
= 564.2
