The sides of two similar polygons are in the ratio 5 : 2. If the area of the smaller polygon is 576 ft2, what is the area of the larger polygon?

based on context clues you gave i'm assuming the answer would be c.

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.

so, converting firstly the mixed fractions to improper fractions and then "adding".

there were a lot of them but the first one to pop up on a google search was bts
