Answer: B
Step-by-step explanation:
YOU MINUS 4 -4 WHICH IS -8 SO ITS B
Answer:

Step-by-step explanation:
<u>Similar Triangles</u>
By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:

Simplifying both fractions

Solving for x

The ratio of the surface area to the volume will decrease
240 because 8 times 30 equals 240
