base edge? height?

Surface area of a square pyramid:

s = length of base edge.

h = height of pyramid from base to top.

A = surface area.

√ = square root, root of 2, opposite of square.

² = square, power of 2, times itself once.

√n × √n = n

n × n = n²

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.
