The volumes of two similar solids are 729 m3 and 125 m3. the surface area of the larger solid is 324 m2. what is the surface area of the smaller solid?
a) 56 m2
b) 100 m2
c) 500 m2
d) 200 m2

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.

2y+y=5

add 2y and y
