The surface area of cone B is 10 km², and Cone B is the image of cone A after dilation by a scale factor of 1/2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Cone B is the image of cone A after dilation by a scale factor of 1/2, hence:
Surface area of cone B = 40 km² * (1/2)² = 10 km²
The surface area of cone B is 10 km², and Cone B is the image of cone A after dilation by a scale factor of 1/2

Step-by-step explanation:
know the normal large sample condition is not met and also there are outliers
Well if you write the statement as an equation then that will get you
3*x^2 = 12x
Now we just solve. You can divide both sides by 3x and that gives you x = 4
Answer:
x > -10
Step-by-step explanation:
2 + x > -8
x > -8 - 2
x > -10
They are adjacent because he share a vertex and a common side, and x=15° because 90°/(2+4)= 15
