Aright square pyramid has a surface area of 80 m. if the lengths of the sides of the base and the slant height of the pyramid are multiplied by 5, what is the surface area of the new cone? a.2000 m b.1600 m c.800 m d.400 m

A: 2000

Step-by-step explanation:

First you need to solve 5^2 (the scale factor multiplied by itself) or 25. Then multiply the new scale factor by the initial surface area, 80.

25*80= 2000

56

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
