Two pyramids are similar. Their base edges are a ratio of 3:5. Find the ratio of their surface area.

9/25

Step-by-step explanation:

Two pyramids are similar. Their base edges are a ratio of 3:5. Find the ratio of their surface area.

The ratio of the surface area is calculated as the square of the ratio of the edges

Hence,

Ration of surface area = 3²/5²

= 9/25

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
