Help pls this is really confusing

Two cones have a scale factor of 2 : 5. The smaller cone has a surface area of 96π square yards. Find the surface area of the larger cone. Write your answer in terms of π.

Step-by-step explanation:

so the smaller one is two right? we can divide 96 by 2 to get 48 for each one

to find the bigger we simply multiply 48 by 5 to get 240

d

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
