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

Answer:12.33333333333
Step-by-step explanation:
8x - 2 = 14x - 76
74 = 6x
12.333 = x
Answer:
We have (60/100)·x - 17 = - 65;
Then (6/10)·x = 17 - 65;
(3/5)·x = - 48;
x = (5/3)·(-48);
x = 5·(-16);
x = - 80;
Step-by-step explanation:
Use this formula a2 − b2 = (a + b)(a − b)
<span>(x+1)^2-(x-1)^2 in this case, a = x+1, b = x-1</span>
<span>= [(x+1) + (x-1)] * [(x+1) – (x-1)]</span>
=(x +1 + x – 1) *(x +1 – x +1)
= 2x * 2
<span>=4x</span>
